The present disclosure relates to the field of communication technology, and particularly relates to a transparent antenna and a communication system.
With the continuous development of mobile communication technology, additional functional attributes for a glass window are increasingly remarkable. A combination application of an antenna and the glass window becomes one of the most representative applications. Since a traditional antenna can not be transparent, when the traditional antenna is used in combination with a transparent glass window, firstly, beauty of an overall environment of the glass window is influenced, secondly, due to a strong attenuation characteristic of the glass to electromagnetic waves, when the antenna is tightly attached to the glass window, the antenna cannot obtain effective electromagnetic energy radiation, and finally a problem of low gain of the antenna is caused. Therefore, designing an antenna scheme that can ensure high gain performance of the antenna and also ensure transparency of the antenna will become a trend of beautifying an antenna of 4G/5G.

The use of “first,” “second,” and the like in the present disclosure is not intended to indicate any order, quantity, or importance, but rather is used to distinguish one element from another. Also, the use of the words “a,” “an,” or “the” and similar referents do not denote a limitation of quantity, but rather denote the presence of at least one. The word “comprising” or “including”, and the like, means that the element or item preceding the word includes the element or item listed after the word and its equivalent, but does not exclude other elements or items. The terms “connected” or “coupled” and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. Terms “upper/on”, “lower/below”, “left”, “right”, and the like are used only to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
The embodiments of the present disclosure are not limited to the embodiments shown in the drawings, but include modifications of configurations formed based on a manufacturing process. Thus, regions illustrated in the drawings have schematic properties, and shapes of the regions shown in the drawings illustrate specific shapes of regions of elements, but are not intended to be limiting.
Embodiments of the present disclosure provide a transparent antenna that may be used in glass window systems including, but not limited to, automobiles, trains (including high-speed rail), aircraft, buildings, or the like. The transparent antenna may be fixed to an inner side of the glass window (a side closer to the room). Since the optical transmittance of the transparent antenna is relatively high, the transparent antenna has little influence on the transmittance of the glass window while realizing the communication function, and the transparent antenna also is a trend of beautifying an antenna. The glass window in the embodiment of the present disclosure includes, but is not limited to, double glass, and the type of the glass window may also be single glass, laminated glass, thin glass, thick glass, or the like. In the embodiments of the present disclosure, the application of the glass window attached with the transparent antenna to a subway window system is taken as an example for explanation.
In a first aspect,
It should be noted that the transparent antenna in the embodiment of the present disclosure may be a receiving antenna, a transmitting antenna, or a transceiving antenna that simultaneously transmits and receives signals. In the following description, a case where the transparent antenna is a transmitting antenna is taken an example for illustration. The first electrode layer 11 includes, but is not limited to, a ground electrode layer, and a case where the first electrode layer 11 is the ground electrode layer is taken as an example for illustration in the embodiment of the present disclosure.
In the embodiment of the present disclosure, the first surface and the second surface of the first dielectric layer 10 are parallel to each other; the third surface and the fourth surface of the second dielectric layer 210 are parallel to each other; the fifth surface and the sixth surface of the third dielectric layer 220 are parallel to each other. In
In the embodiment of the present disclosure, since the first antenna dielectric plate 21 of each radiating structure 2 includes the first balun feed structure 212, and the second antenna dielectric plate 22 of each radiating structure 2 includes the second balun feed structure, the first balun feed structure 212 may be fed through the first transmission line 12, and then the first balun feed structure 212 is coupled with the first radiating element 211 to transmit a microwave signal through the first radiating element 211. In a similar way, the second balun feed structure may be fed through the second transmission line, and then the second balun feed structure is coupled with the second radiating element 221 to transmit a microwave signal through the second radiating element 221. The transparent antenna in the embodiment of the present disclosure can effectively improve the radiation efficiency, has a relatively high gain, and can ensure the stability of signal transmission. In addition, the transparent antenna in the embodiment of the present disclosure has the characteristics of high concealment and beauty.
In some examples, at least one of the first electrode layer 11, the first radiating element 211, the first balun feed structure 212, the second balun feed structure, the first transmission line 12, and the second transmission line 13 is of a metal mesh structure. In some implementations, the first electrode layer 11, the first radiating element 211, the first balun feed structure 212, the second balun feed structure, the first transmission line 12 and the second transmission line 13 all adopt the metal mesh structure. By this way, the optical transmittance of the transparent antenna can be further improved.
Furthermore, an orthographic projection, of the hollow-out portions of the first electrode layer 11 in the metal mesh structure on the first surface of the first dielectric layer 10, on the first dielectric layer 10 is completely overlapped with an orthographic projection, of the hollow-out portions of the first transmission line 12 and the second transmission line 13 in the metal mesh structure on the second surface of the first dielectric layer 10, on the first dielectric layer 10. An orthographic projection, of the hollow-out portions of the first balun feed structure 212 in the metal mesh structure on the third surface of the second dielectric layer 210, on the second dielectric layer 210 is completely overlapped with an orthographic projection, of the hollowed-out portions of the first balun feed structure 212 in the metal mesh structure on the fourth surface of the second dielectric layer 210, on the second dielectric layer 210. An orthographic projection, of the hollowed-out portions of the second balun feed structure 222 in the metal mesh structure on the fifth surface of the third dielectric layer 220, on the third dielectric layer 220 is completely overlapped with an orthographic projection, of the hollowed-out portions of the second balun feed structure in the metal mesh structure on the sixth surface of the third dielectric layer 220, on the third dielectric layer 220. In such case, the light transmittance of the transparent antenna can be further improved.
In some examples, in the metal mesh structure, the first metal lines 501 and the second metal lines 502 each have a same line width and a same line thickness, and a spacing between any two adjacent first metal lines 501 or any two adjacent second metal lines 502 may be constant, but may also be variable. For example, each of the first metal lines 501 and the second metal lines 502 has a line width W1 ranging from about 11 μm to about 30 μm and a line thickness ranging from about 0.5 μm to about 10 μm, and a spacing W2 between any two adjacent first metal lines 501 or between any two second metal lines 502 is in a range from about 50 μm to about 250 μm.
Materials of the first base material 10b and the second base material 10c may be the same or different; for example, the first base material 10b and the second base material 10c are flexible films made of a material including, but not limited to, Polyethylene Terephthalate (PET), Polyimide (PI), or the like. In the embodiment of the present disclosure, both the first base material 10b and the second base material 10c being made of PET is taken as an example for illustration. The first base material 10b and the second base material 10c each have a thickness ranging from about 50 μm to about 250 μm. Since the first base material 10b and the second base material 10c are flexible and thus cannot provide good support for the first electrode layer 11, the first transmission lines 12 and the second transmission lines 13, therefore, the first electrode layer 11, the first transmission lines 12 and the second transmission lines 13 are easily deformed, and a desired radiation effect cannot be obtained. Therefore, the first fixing plate 10a is provided to maintain rigidity of the first backplane 1, and a material of the first fixing plate 10a includes, but is not limited to, Polycarbonate (PC), Copolymers of Cycloolefin (COP) or acrylic/Polymethyl Methacrylate (PMMA). A thickness of the first fixing plate 10a ranges from about 1 mm to about 3 mm. Materials of the first adhesive layer and the second adhesive layer may be the same or different, for example, both the first adhesive layer and the second adhesive layer are made of transparent optical adhesive (OCA).
Materials of the third base material 210b and the fourth base material 210c may be the same as the material of the first base material 10b, materials of the third adhesive layer and the fourth adhesive layer may be the same as the material of the first adhesive layer, and a material of the second fixing plate 210a may be the same as the material of the first fixing plate 10a, thus the description thereof is not repeated herein.
Materials of the fifth base material 220b and the sixth base material 220c may be the same as the material of the first base material 10b, materials of the fifth adhesive layer and the sixth adhesive layer may be the same as the material of the first adhesive layer, and a material of the third fixing plate 220a may be the same as the material of the first fixing plate 10a, and the description thereof is not repeated herein.

The second conductive portion is electrically connected to the second connection pad 15b, for example, the second conductive portion is soldered to the second connection pad 15b, so that the second dipole arm 211b is electrically connected to the first electrode layer 11 through the second conductive portion and the second connection pad 15b. The third conductive portion is electrically connected to the third connection pad 15c, for example, the third conductive portion is soldered to the third connection pad 15c, so that the third dipole arm 221a is electrically connected to the first electrode layer 11 through the third conductive portion and the third connection pad 15c.

That is, the first radiating element 211, the first director 214a, and the second director 214b are disposed in a same layer and made of a same material. In such case, patterns of the first radiating element 211, the first director 214a, and the second director 214b may be formed by a process including, but not limited to, imprinting or etching. Meanwhile, the second antenna dielectric plate 22 includes a second metal layer disposed on the fifth surface of the third dielectric layer 220, the second metal layer includes the second radiating element 221, the third director 224a, and the fourth director 224b. That is, the second radiating element 221, the third director 224a, and the fourth director 224b are disposed in a same layer and made of a same material. In such case, patterns of the second radiating element 221, the third director 224a, and the fourth director 224b may be formed by a process including, but not limited to, imprinting or etching.
In some examples, the first balun feed structure 212 in the first antenna dielectric plate 21 and the second balun feed structure in the second antenna dielectric plate 22 each may adopt a strip-shaped balun feed structure. In some implementations, the first balun feed structure 212 and the second balun feed structure each are provided with at least one bending structure, so as to increase areas of orthographic projections of the first balun feed structure 212 and the first radiating element 211 on the second dielectric layer 210, and areas of orthographic projections of the second balun feed structure and the second radiating element 221 on the third dielectric layer 220, thereby improving feed effect of the first balun feed structure 212 and the second balun feed structure.
In some examples, the first balun feed structure 212 is connected to the first transmission line 12 by means of soldering; and/or the second balun feed structure is connected to the second transmission line 13 by means of soldering. The case where the first balun feed structure 212 being connected to the first transmission line 12 by means of soldering, and the second balun feed structure being connected to the second transmission line 13 by means of soldering is taken as an example for illustration. By means of soldering, good electrical connection between the first balun feed structure 212 and the first transmission line 12 can be effectively ensured, and good electrical connection between the second balun feed structure and the second transmission line 13 can also be effectively ensured.

The printed circuit board 4 is fixed to the first side plate 102 by bolting, that is, threaded holes may be formed in the printed circuit board 4 and the first side plate 102, and bolts 402 pass through the threaded holes and are tight with nuts, so that the printed circuit board 4 and the first side plate 102 are fixedly connected.
It should be noted that, since the printed circuit board 4 is fixed on the surface of the first side plate 102 away from the second side plate 103, in such case, through holes penetrating through the first side plate 102 are formed at positions corresponding to the second feeding port 413 of the first feeding unit 41 and the second feeding port 423 of the second feeding unit 42, so that the second feeding port 413 of the first feeding unit 41 can be electrically connected to the first transmission line 12 through the through hole of the first side plate 102 by using a connection component 401, and similarly, the second feeding port 423 of the second feeding unit 42 can be electrically connected to the second transmission line 13 through the through hole of the first side plate 102 by using a connection component 401.

In the process of receiving a signal by the communication system, after receiving the signal, the transparent antenna 1 transmits the signal to the filtering unit, the filtering unit filters noise waves from the signal received by the antenna and then transmits the signal to the signal amplifier and the power amplifier, the signal amplifier adjusts the gain of the signal received by the transparent antenna 1 to increase the signal-to-noise ratio of the signal; the power amplifier amplifies the power of the signal received by the transparent antenna 1. The signal received by the transparent antenna 1 is processed by the power amplifier and the signal amplifier and then transmitted to the radio frequency transceiver, and the radio frequency transceiver transmits the signal to the transceiver unit.
In some examples, the signal amplifier may include multiple types of signal amplifiers, such as a low noise amplifier, which is not limited herein.
