In response to the above-referenced technical inadequacies, the present disclosure provides a co-construction antenna module.
In one aspect, the present disclosure provides a co-construction antenna module including: a carrier, a first patch antenna group, a second patch antenna group, a first dipole antenna group, and a second dipole antenna group.

Referring to FIG. 1 to FIG. 3, FIG. 1 is a perspective schematic view of a co-construction antenna module according to a first embodiment of the present disclosure, FIG. 2 is another perspective schematic view of the co-construction antenna module according to the first embodiment of the present disclosure, and FIG. 3 is a top schematic view of a co-construction antenna module according to the first embodiment of the present disclosure. The first embodiment of the present disclosure provides a co-construction antenna module U including: a carrier 1, a first patch antenna group 2, a second patch antenna group 3, a first dipole antenna group 4, and a second dipole antenna group 5. The carrier 1 can be a multilayer low temperature co-fired ceramic substrate (LTCC). In addition, in other embodiments, the carrier 1 may be a low dielectric constant and low loss PCB board, such as but not limited to a multilayer epoxy resin composed of a glass fiber substrate (FR-4). Thereby, the co-construction antenna module U provided by the present disclosure can co-construct the first patch antenna group 2, the second patch antenna group 3, the first dipole antenna group 4 and the second dipole antenna group 5 in the carrier 1 formed by the multi-layer low-temperature co-fired ceramic substrate by using a low-temperature co-fired ceramic technology. In other words, the first patch antenna group 2, the second patch antenna group 3, the first dipole antenna group 4, and the second dipole antenna group 5 can form an integrated co-fired ceramic antenna.
Next, referring to FIG. 1 and FIG. 2, the carrier 1 may include a first surface 11, a second surface 12 relative to the first surface 11, and a surrounding side 13 connected between the first surface 11 and the second surface 12. The first patch antenna group 2 may include a plurality of first patch antennas 20 disposed on the carrier 1, and the plurality of first patch antennas 20 are disposed on at least one of the first surface 11 and the second surface 12. The second patch antenna group 3 may include a plurality of second patch antennas 30 disposed on the carrier 1, and the plurality of second patch antennas 30 are disposed on at least one of the first surface 11 and the second surface 12. Further, in the first embodiment of the present disclosure, the plurality of first patch antennas 20 may be disposed on the first surface 11, and the plurality of second patch antennas 30 may be disposed on the first surface 11, but the present disclosure is not limited thereto. Thereby, since the first patch antenna 20 and the second patch antenna 30 in the first embodiment are all disposed on the first surface 11, a radiation pattern generated by the first patch antenna 20 and the second patch antenna 30 may formed along a Z direction.
Then, referring to FIG. 3 and FIG. 4, and FIG. 4 is a side schematic view of a co-construction antenna module according to the first embodiment of the present disclosure. The first dipole antenna group 4 can be disposed in the carrier 1, and the second dipole antenna group 5 can be disposed in the carrier 1. For example, when the carrier 1 is a multilayer low temperature co-fired ceramic substrate, the first dipole antenna group 4 and the second dipole antenna group 5 may be disposed on one of the layers of the low temperature co-fired ceramic substrate. Further, the first dipole antenna group 4 and the second dipole antenna group 5 may be located on the same layer of the low temperature co-fired ceramic substrate, or the first dipole antenna group 4 and the second dipole antenna group 5 are located on different layers of the low temperature co-fired ceramic substrate, and the present disclosure is not limited thereto.

The plurality of first dipole antennas 41, the plurality of second dipole antennas 42, a plurality of third dipole antennas 51, and a plurality of fourth dipole antennas 52 may be disposed adjacent to the surrounding side 13 of the carrier 1. Further, the first patch antenna group 2 has a first operating band, the second patch antenna group 3 has a second operating band, the first dipole antenna group 4 has a third operating band, and the second dipole antenna group 5 has a fourth operating band. Further, the frequency of the first operating band may be less than the frequency of the second operating band, and the frequency of the third operating band may be less than the frequency of the fourth operating band. Furthermore, for example, the first operating band may be a millimeter-wave low-frequency, the second operating band may be a millimeter-wave high-frequency, the third operating band may be a millimeter-wave low-frequency, and the fourth operating band may be a millimeter-wave high-frequency. For example, in the present disclosure, the first patch antenna group 2 may have a first operating frequency band of 28 GHz, the second patch antenna group 3 may have a second operating frequency band of 39 GHz, the first dipole antenna group 4 may have a third operating frequency band of 28 GHz, and the second dipole antenna group 5 may have a fourth operating frequency band of 39 GHz, but the present disclosure is not limited thereto.

In addition, a vertical projection of the first patch antenna group 2 on the second surface 12 of the carrier 1 can form a first projection area, a vertical projection of the second patch antenna group 3 on the second surface 12 of the carrier 1 can form a second projection area, a vertical projection of the first dipole antenna group 4 on the second surface 12 of the carrier 1 can form a third projection area, and a vertical projection of the second dipole antenna group 5 on the second surface 12 of the carrier 1 can form a fourth projection area. For example, the first projection area and the third projection area and/or the fourth projection area do not overlap each other, and the second projection area and the third projection area and/or the fourth projection area do not overlap each other, but the present disclosure is not limited thereto.
As mentioned above, referring to FIG. 3, for example, the surrounding side 13 of the carrier 1 may have a rectangular shape, and the surrounding side 13 may include a first side 131, a second side 132 connected to the first side 131, a third side 133 connected to the second side 132, and a fourth side 134 connected between the third side 133 and the first side 131. In the first embodiment of the present disclosure, the plurality of first dipole antennas 41 may be arranged along the first side 131, the plurality of second dipole antennas 42 may be arranged along the second side 132, the plurality of third dipole antennas 51 may be arranged along the third side 133, and the plurality of fourth dipole antennas 52 arranged along the fourth side 134.

Next, referring to FIG. 5, FIG. 5 is a perspective schematic view of a first patch antenna of the co-construction antenna module according to the first embodiment of the present disclosure. The first patch antenna 20 may include a first radiator 201 and a first feed pin 202 connected to the first radiator 201 to feed the signal to the first radiator 201 using the first feed pin 202.

In addition, it should be noted that other structures of the co-construction antenna module U provided by the second embodiment are similar to the foregoing embodiments, and are not described herein again.

In other words, by the arrangement of the fifth dipole antenna 43 and the sixth dipole antenna 53, a radiation pattern direction of the first dipole antenna group 4 and the second dipole antenna group 5 can be increased.
Thereby, in the third embodiment of the present disclosure, the radiation pattern along the Z direction can be generated by the first patch antenna group 2 and the second patch antenna group 3, and a radiation pattern in the an X direction, a Y direction, and a negative Y direction can be generated by the first dipole antenna 41, the second dipole antenna 42, and the fifth dipole antenna 43, respectively. A radiation pattern along the negative X direction, the Y direction, and the negative Y direction can be generated by the third dipole antenna 51, the fourth dipole antenna 52, and the sixth dipole antenna 53, respectively.
