The antenna apparatus 100 may be, but is not limited to, connected to the circuit board 400, small board, or mainboard of the electronic device 10. As shown in FIGS. 2 and 3, FIG. 2 is a first structural schematic view of an antenna apparatus provided by an embodiment of the present disclosure, and FIG. 3 is a schematic view of a connection of a feed source shown in FIG. 2. The antenna apparatus 100 may include a feed source 110, a dielectric substrate 120, a first antenna array 130 and a second antenna array 140.

As shown in FIG. 3, the feed source 110 may be disposed on the dielectric substrate 120. In this case, a distance between the feed source 110 and the first antenna array 130 and the second antenna array 140 disposed on the dielectric substrate 120 is relatively close, which facilitates the design of the wiring of the feed source 110.

As shown in FIG. 2, the feed source 110 may not be disposed on the dielectric substrate 120. For example, the feed source 110 may be disposed on a mainboard of the antenna apparatus 100, and the feed source may also be disposed on the circuit board 400 of the electronic device 10. The embodiments of the present disclosure do not limit the specific location of the feed source 110.

The feed source 110 may be directly or indirectly electrically connected to the first antenna array 130, and the feed source 110 may provide an excitation signal to excite the first antenna array 130 to transmit a first wireless signal. The feed source 110 may also be directly or indirectly electrically connected to the second antenna array 140 to stimulate the second antenna array 140 to transmit a second wireless signal.

The feed source 110 may be directly or indirectly electrically connected to the first antenna array 130 and the second antenna array 140 through a conductive connector such as a metal wiring, a feed network, a metal plated through hole, etc.

The feed source 110 may also be coupled to the first antenna array 130 and the second antenna array 140 to feed the excitation signal to the first antenna array 130 and the second antenna array 140. The feed source 110 may also be directly or indirectly electrically connected to the first antenna array 130 to excite the first antenna array 130 to transmit the first wireless signal. In this case, the second antenna array 140 may be electrically connected to the first antenna array 130 or be connected by coupling feed to enable the second antenna array 140 to transmit the second wireless signal.

The embodiments of the present disclosure do not limit the specific electrical connection relationship between the feed source 110, the first antenna array 130 and the second antenna array 140.

The dielectric substrate 120 may include a first sub-substrate 121 and a second sub-substrate 122 connected to each other. An extension direction of the second sub-substrate 122 may intersect with an extension direction of the first sub-substrate 121, such that the second sub-substrate 122 and the first sub-substrate 121 are on different planes.

The first sub-substrate 121 and the second sub-substrate 122 may form an angle of 90 degrees or approximately 90 degrees. In this case, on a cross-section of the dielectric substrate 120, the first sub-substrate 121 and the second sub-substrate 121 may be L-shaped or close to L-shaped.

The first sub-substrate 121 and the second sub-substrate 122 may also form other angles, such as an acute angle or an obtuse angle. The embodiments of the present disclosure do not limit the specific connection method of the first sub-substrate 121 and the second sub-substrate 122.

The first sub-substrate 121 may carry the first antenna array 130, and the first antenna array 130 may be disposed on the first sub-substrate 121. For example, the first antenna array 130 may be disposed on an upper surface of the first substrate 121. The first antenna array 130 may be provided with a feed point 150, and the feed point 150 may be electrically connected to the feed source 110, such that the first antenna array 130 may be electrically connected to the feed source 110 through the feed point 150 to transmit a first wireless signal.

The feed point 150 may be a feed pad or a feed ball. The feed point 150 and the first antenna array 130 may be disposed oppositely on two sides of the first sub-substrate 121. For example, the feed point 150 may be disposed on a lower surface of the first sub-substrate 121.

The second sub-substrate 122 may carry the second antenna array 140, and the second antenna array 140 may be disposed on the second sub-substrate 122. For example, the second antenna array 140 may be disposed on an outer side of the second sub-substrate 122. The second antenna array 140 may also be electrically connected to the feed source 110 to transmit the second wireless signal.

A feed point may also be provided on the second antenna array 140, so as to be electrically connected to the feed source 110 through the feed point. The second antenna array 140 may also be electrically connected to the feed source 110 through coupling feed.

The second antenna array 140 may also share the feed point 150 with the first antenna array 130, so as to be electrically connected to the feed source 110 through the feed point 150.

For example, as shown in FIG. 4, which is a schematic view of an electrical connection of the antenna apparatus shown in FIG. 2. The second antenna array 140 may be connected to the feed point 150 through a first feed network 160. The first feed network 160 may be bent and extended from the second sub-substrate 122 toward the first sub-substrate 121. The second antenna array 140 is connected to the feed source 110 through the first feed network 160 and the feed point 150 and transmits the second wireless signal.

In the antenna apparatus 100 of the embodiments of the present disclosure, the feed point 150 is provided on the first sub-substrate 121, and the second antenna array 140 provided on the second sub-substrate 122 is connected to the feed source 110 through the feed point 150, such that there is no need to arrange the feed point 150 on the second sub-substrate 122, which may reduce the difficulty of connecting the second antenna array 140 to the feed source 110.

The first wireless signal and the second wireless signal may be wireless signals in the same frequency band. The first wireless signal and the second wireless signal may also be wireless signals in different frequency bands. The embodiments of the present disclosure do not limit this.

The first antenna array 130 and the second antenna array 140 may be millimeter wave antenna arrays. According to the provisions of the 5GPP TS 38.103 (5th Generation Partnership Project) agreement, the 5th generation mobile networks (referred to as 5G) mainly adopts two frequency bands: FR1 frequency band and FR2 frequency band. A frequency range of the FR1 band is 450 MHz 6 GHz, also called the sub-6 GHz band; a frequency range of the FR2 band is 24.25 GHz 52.6 GHz, usually called millimeter wave (mm Wave). 3GPP Release 15 standardizes current 5G millimeter wave frequency bands: N257 (26.5-29.5 GHz), N258 (24.25-27.5 GHz), N261 (27.5-28.35 GHz) and N260 (37-40 GHz).

The wavelength range corresponding to the above-mentioned millimeter waves is 1 mm˜10 mm. Since the wavelength of millimeter waves is short, they are easily being obstructed during transmission. Therefore, both the first antenna array 130 and the second antenna array 140 may include a plurality of millimeter wave antenna units arranged in an array.

When the first antenna array 130 includes the plurality of millimeter wave antenna units arranged in an array, the number of the feed point 150 may be multiple, so as to facilitate integration with the plurality of millimeter wave antenna units of the first antenna array 130 one by one, which allows one millimeter wave antenna unit to be connected to one feed point 150.

When the second antenna array 140 is connected to the feed point 150 through the first feed network 160, each millimeter wave antenna unit on the second antenna array 140 may be connected to one feed point 150 through one corresponding feeder on the first feed network 160. Each millimeter-wave antenna unit on the second antenna array 140 may also be connected to one millimeter-wave antenna unit on the first antenna array 130 through one corresponding feeder on the first feed network 160, such that one millimeter wave antenna unit on the first antenna array 130 is indirectly connected to one feed point 150.

The antenna apparatus 100 of the embodiments of the present disclosure effectively enhances transmission performance of the first antenna array 130 and the second antenna array 140 by arranging multiple millimeter wave antenna units at intervals. By arranging multiple millimeter wave antenna units on the dielectric substrate 120, transmission requirements of 5G millimeter wave band of the first antenna array 130 and the second antenna array 140 may be met. The “transmission” mentioned above for transmitting wireless signals includes receiving wireless signals, transmitting wireless signals, and receiving and transmitting wireless signals simultaneously.

As shown in FIG. 2 and FIG. 5, FIG. 5 is a schematic view of a radiation direction of the antenna apparatus shown in FIG. 2. When the first antenna array 130 is electrically connected to the feed source 110 and transmits the first wireless signal, the first antenna array 130 may have a first radiation direction A1. The first radiation direction A1 may be an outward extension direction of the first sub-substrate 121 of the dielectric substrate 120, the outward side of the first sub-substrate 121 may form a first radiation area. Similarly, when the second antenna array 140 is electrically connected to the feed source 110 and transmits the second wireless signal, the second antenna array 140 may have a second radiation direction A2. The second radiation direction A2 may be may be an outward extension direction of the second sub-substrate 122 of the dielectric substrate 120, the outward side of the second sub-substrate 122 may form a second radiation area.

The first radiation direction A1 may be a main radiation direction of the first antenna array 130, and the second radiation direction A2 may be a main radiation direction of the second antenna array 140.

Since the extension direction of the first sub-substrate 121 intersects with the extension direction of the second sub-substrate 122, most of the first radiation area and most of the second radiation area do not overlap, and the first radiation direction A1 of the first antenna array 130 is different from the second radiation direction A2 of the second antenna array 140.

In the electronic device 10 and the antenna apparatus 100 in the embodiments of the present disclosure, the first antenna array 130 is disposed on the first sub-substrate 121 of the dielectric substrate 120, the second antenna array 140 is disposed on the second sub-substrate 122 of the dielectric substrate 120, and the first antenna array 130 and the second antenna array 140 are electrically connected to the feed source 110, such that the first antenna array 130 has the first radiation direction A1, the second antenna array 140 has the second radiation direction A2. The second radiation direction A2 is different from the first radiation direction A1. Based on this, the antenna apparatus 100 of the embodiments of the present disclosure, on the one hand, has two different radiation directions, allowing the antenna apparatus 100 to cover a wider signal direction and the radiation performance of the antenna apparatus 100 being better. On the other hand, the extension direction of the first sub-substrate 121 intersects with the extension direction of the second sub-substrate 122, thus the dielectric substrate 120, the first antenna array 130 and the second antenna array 140 may form a special-shaped antenna. The special-shaped antenna may be designed based on the circuit board of the electronic device 10, such that the special-shaped antenna does not require improvement of the circuit board 400 of the electronic device 10, and the special-shaped antenna has better adaptability. Moreover, as the second antenna array 140 is disposed on the first sub-substrate 121 interconnected with the second sub-substrate 122, the second antenna array 140 may be fixed on an installation object through the second sub-substrate 122 and the first sub-substrate 121, which may reduce installation difficulty of the second antenna array 140.

As shown in FIG. 6 and FIG. 7, FIG. 6 is a second structural schematic view of an antenna apparatus provided by an embodiment of the present disclosure, and FIG. 7 is a third structural schematic view of an antenna apparatus provided by an embodiment of the present disclosure. In addition to the first sub-substrate 121 and the second sub-substrate 122, the dielectric substrate 120 may also include one or more third sub-substrates 123. Correspondingly, the antenna apparatus 100 may also include a third antenna array 170, in addition to the first antenna array 130 and the second antenna array 140.

An extension direction of each third sub-substrate 123 may intersect with the extension direction of the first sub-substrate 121 or the extension direction of the second sub-substrate 122. Therefore, any third sub-substrate 123 is not coplanar with the first sub-substrate 121 or the second sub-substrate 122.

As shown in FIG. 6 and FIG. 7, when the third sub-substrate 123 is perpendicular or approximately perpendicular to the first sub-substrate 121 and the second sub-substrate 122, the first sub-substrate 121, the second sub-substrate 122 and the third sub-substrate 123 may form an X-Y-Z coordinate system.

The third sub-substrate 123 may not be perpendicular to the first sub-substrate 121 and the second sub-substrate 122. For example, an angle between the third sub-substrate 123 and the first sub-substrate 121 and the second sub-substrate 122 may be an acute or an obtuse angle. The embodiments of the present disclosure do not limit the specific positional relationship between the third sub-substrate 123, the first sub-substrate 121, and the second sub-substrate 122. As long as the extension direction of the third sub-substrate 123 intersects with the extension direction of the first sub-substrate 121, the solutions are all within the protection scope of the present disclosure.

The first sub-substrate 121 and the second sub-substrate 122 of the dielectric substrate 120 may be integrally formed together. The first sub-substrate 121, the second sub-substrate 122, and one or more third sub-substrates 123 may also be integrally formed together.

The number of the third antenna array 170 may not be greater than the number of one or more third sub-substrates 123, and each third antenna array 170 may be disposed on one third sub-substrate 123.

As shown in FIG. 6, when the number of the third antenna array 170 is one or more and equal to the number of the third sub-substrate 123, one third antenna array 170 may correspond to one third sub-substrate 12, and each third antenna array 170 may be disposed on each third sub-substrate 123.

For another example, as shown in FIG. 7, when the number of the third sub-substrate 123 is one, the number of the third antenna array 170 may be less than the number of the third sub-substrate 123 and may be zero. In this case, the antenna apparatus 100 may not include the third antenna array 170. In other words, the third antenna array 170 may not be provided on the third sub-substrate 123, and the third sub-substrate 123 may be used as a wiring flexible board to realize the electrical connection between the feed point 150 and the feed source 110.

In the antenna apparatus 100 of the embodiments of the present disclosure, when the number of sub-substrates included in the dielectric substrate 120 is greater than the number of antenna arrays, some sub-substrates of the dielectric substrate 120 may not be provided with antenna arrays. The sub-substrates on the dielectric substrate 120 that are not provided with antenna arrays may play a role in assembling, providing a feed network, etc.

The specific number of the third antenna array 170 and the third sub-substrate 123 in the embodiments of the present disclosure are not limited to the above examples, and the embodiments of the present disclosure do not specifically limit this.

As shown in FIG. 8 in combination with FIG. 6, FIG. 8 is a schematic view of a radiation direction of the antenna apparatus shown in FIG. 6. When the third antenna array 170 of the antenna apparatus 100 is disposed on the third sub-substrate 123, the third antenna array 170 may be directly or indirectly electrically connected to the feed source 110, or the third antenna array 170 may also be connected to the feed source 110 through a coupling way to realize feeding, or the third antenna array 170 may also be coupled and connected with the first antenna array 130 or the second antenna array 140 to realize feeding, such that the third antenna array 170 may transmit the third wireless signal and have a third radiation direction A3.

The third radiation direction A3 may be an outward extension direction of the third sub-substrate 123 of the dielectric substrate 120, which may form a third radiation area. The third radiation direction A3 may be a main radiation direction of the third antenna array 170.

Since the extension direction of the third sub-substrate 123 intersects with the extension directions of the first sub-substrate 121 and the second sub-substrate 122, most of the third radiation area and the first radiation area and the second radiation area do not overlap. The third radiation direction A3 of the third antenna array 170 is different from the first radiation direction A1 of the first antenna array 130 and the second radiation direction A2 of the second antenna array 140.

The antenna apparatus 100 of the embodiments of the present disclosure includes the first antenna array 130 with the first radiation direction A1, the second antenna array 140 with the second radiation direction A2, and the third antenna array 170 with the third radiation direction A3. The antenna apparatus 100 includes three different radiation directions. The antenna apparatus 100 covers a wider signal direction, which may improve the radiation performance of the antenna apparatus 100.

As shown in FIG. 9 and FIG. 10, FIG. 9 is a fourth structural schematic view of an antenna apparatus provided by an embodiment of the present disclosure, FIG. 10 is a structural schematic view of a mainboard shown in FIG. 9. The antenna apparatus 100 may also include a motherboard 180.

As shown in FIG. 10, the mainboard 180 may include a first surface 181 and a third surface 183 arranged oppositely, as well as a second surface 182, a fourth surface 184, and a fifth surface disposed between the first surface 181 and the third surface 183. Extending directions of the second surface 182, the fourth surface 184, the fifth surface 185 and the sixth surface 186 may intersect with the extending directions of the first surface 181 and the third surface 183, such that the second surface 182, the fourth surface 184, the fifth surface 185 and the sixth surface 186 are not coplanar with the first surface 181 and the third surface 183.

The second surface 182, the fourth surface 184, the fifth surface 185 and the sixth surface 186 may be directly or indirectly connected to the first surface 181 and the third surface 183. In this case, the mainboard 180 may be a rectangular thin plate.

The mainboard 180 may also be a structure of other shapes, such as but not limited to a prism, a pentagon, a hexagon, a polygon, etc. The mainboard 180 may also include more surfaces, such as a seventh surface, an eighth surface, etc. The present disclosure does not limit the specific structure of the mainboard 180.

The mainboard 180 may carry the dielectric substrate 120 and the antenna array. The mainboard 180 may be, but is not limited to, at least part of the carrier board of the middle frame 300 of the electronic device 10, at least part of the antenna bracket of the electronic device 10, or at least a portion of the circuit board 400 of the electronic device 10. For example, the circuit board 400 of the electronic device 10 may include the mainboard 180 of the antenna apparatus 100.

The embodiments of the present disclosure do not limit the specific structure of the mainboard 180, and any structure that may carry the dielectric substrate 120 and the antenna array is within the protection scope of the embodiments of the present disclosure.

As shown in FIG. 9, the first surface 181 and the second surface 182 of the mainboard 180 are connected to each other, and the extension direction of the second surface 182 may intersect with the extension direction of the first surface 181. Thus, the first sub-substrate 121 of the dielectric substrate 120 may be connected to the first surface 181 of the mainboard 180. For example, a lower surface of the first sub-substrate 121 may be attached to and connected to the first surface 181; the second sub-substrate 122 of the dielectric substrate 120 may be connected to the mainboard 180. For example, an inner surface of the second sub-substrate 122, may be attached to and connected to the second surface 182.

When the dielectric substrate 120 also includes one or more third sub-substrates 123, each third sub-substrate 123 may be connected to other suitable surfaces of the mainboard 180 that are different from the first surface 181 and the second surface 182. For example, the third sub-substrate 123 may be connected to the fourth surface 184, the fifth surface 185, the sixth surface 186 . . . .

The extension direction of the surface connected to the third sub-substrate 123 of the mainboard 180 may intersect with the extension directions of the first surface 181 and the second surface 182, such that when the third array antenna 170 is disposed on the third sub-substrate 123, the radiation direction of the third antenna array 170 is different from the radiation directions of the first antenna array 130 and the second antenna array 140.

In the antenna apparatus 100 of the embodiments of the present disclosure, the first antenna array 130 is connected to the first surface 181 of the mainboard 180 through the first sub-substrate 121, and the second antenna array 140 is connected to the second surface 182 of the mainboard 180 through the second sub-substrate 122. A size of the first antenna array 130 and the second antenna array 140 in a thickness direction of the mainboard 180 is small, which may reduce a cross-sectional height of the antenna apparatus 100 and achieve miniaturization of the antenna apparatus 100. Moreover, due to the size of the surface 182 of the mainboard 180 in the thickness direction of the mainboard 180 is small, it is difficult to fix the antenna radiator on the second surface 182. However, in the embodiments of the present disclosure, the second sub-substrate 122 and the first sub-substrate 121 are connected to each other, such that the second sub-substrate 122 may be connected to the second surface 182 of the mainboard 180 through the second sub-substrate 122 and the first sub-substrate 121, which may reduce installation difficulty of the second antenna array 140.

Based on the structure of the antenna apparatus 100 described above, as shown in FIG. 11, which is a schematic structural view of a fifth antenna apparatus provided by an embodiment of the present disclosure. The first antenna array 130 and the feed point 150 may be connected to the first surface 181 of the mainboard 180 through the first sub-substrate 121. The feed source 110 may be disposed on the third surface 183 of the mainboard 180. The feed source 110 and the first antenna array 130 may be arranged on opposite surfaces of the mainboard 180.

As shown in FIG. 10, the motherboard 180 may also be provided with a metal plated hole 187 penetrating the first surface 181 and the third surface 183. Metal plating operation may be performed on a wall of the metal plated hole 187, such that the feed point 150 on the first surface may be electrically connected to the feed source 110 on the third surface 183 through the hole wall of the metal plated hole 187, thereby realizing electrical connection between the feed source 110 and the first antenna array 130 and the second antenna array 140.

The feed source 110 may also be coupling fed with the first antenna array 130 through the metal plated hole 187. Thus, the feed source 110 and the first antenna array 130 may be coupling fed without using physical electrical devices.

The feed 110 may be disposed directly opposite the first antenna array 130 such that the metal plated hole 187 may pass vertically along the thickness direction of the mainboard 180.

A number of metal plated hole 187 may not be less than a number of the feed point 150, and each feed point 150 may be electrically connected to the feed source 110 through one metal plated hole 187.

The antenna apparatus 100 may also include a feed terminal 111 electrically connected to the feed source 110. The feed terminal 111 may be disposed on the third surface 183 of the mainboard 180.

An end of the metal plated hole 187 may be electrically connected to the feed point 150, and another end of the metal plated hole 187 may be electrically connected to the feed terminal 111. Therefore, the first antenna array 130 may be electrically connected to the feed source 110 through the feed point 150, the metal plated hole 187 and the feed terminal 111.

In the antenna apparatus 100 of the embodiments of the present disclosure, the feed 110 and the first antenna array 130 are disposed on different surfaces of the mainboard 180. The first antenna array 130 may be disposed directly opposite the feed source 110, and direct or indirect connection may be realized through the metal plated hole 187. Therefore, the difficulty of electrical connection between the first antenna array 130 and the feed source 110 may be reduced, and the number of wirings required for electrical connection between the two may be reduced.

As shown in FIG. 12, which is a sixth structural schematic view of an antenna apparatus provided by an embodiment of the present disclosure.

The extension sub-substrate 124 may be connected to the first sub-substrate 121 and extend in a direction toward the feed source 110. The extension sub-substrate 124 and the first sub-substrate 121 may be located on a same side of the second sub-substrate 122. The extension sub-substrate 124 may be connected to the first surface 181 of the mainboard 180, for example, a lower surface of the extension sub-substrate 124 may be attached to the first surface 181.

The extension sub-substrate 124 may be a flexible feed board, and the feed point 150 of the first antenna array 130 may be electrically connected to the feed source 110 through the extension sub-substrate 124.

The second feed network 190 may be electrically connected to the feed source 110 through the extension sub-substrate 124.

In the antenna apparatus 100 according to the embodiments of the present disclosure, the feed 110 and the first antenna array 130 are disposed on the same surface of the mainboard 180. The size of the antenna apparatus 100 in the thickness direction is smaller, which facilitates miniaturization of the antenna apparatus 100.

In addition to being disposed on the first surface 181 or the third surface 183 of the mainboard 180, the feed source 110 may also be disposed on the dielectric substrate 120, for example, on the first sub-substrate 121 of the dielectric substrate 120. In this case, the antenna apparatus 100 may further include a third feed network (not shown in the drawings). The third feed network may be disposed inside the first sub-substrate 121. The third feed network may be connected to the first antenna array 130 disposed on the first sub-substrate 121 and the feed 110. The second antenna array 140 may also be electrically connected to the feed source 110 through the third feed network.

The feed source 110 may also be disposed on other areas of the dielectric substrate 120, such as the second sub-substrate 122 and the third sub-substrate 123. The embodiments of the present disclosure do not specify the specific position of the feed source 110.
