Description

Technical Field

[0001] This utility model relates to a directional antenna, specifically a directional antenna that uses a heat sink as a reflector. Background Art

[0002] In the design of electronic circuits, it is necessary to simultaneously consider the functional requirements of directional antennas and the heat dissipation requirements of electronic components. Faced with these dual needs, a discrete design approach is typically adopted, where heat sinks and antenna reflectors are designed separately. The advantage of this design is that it effectively resolves the conflict between directional antennas and heat dissipation, ensuring that the electronic device has good antenna performance while also guaranteeing efficient component cooling. However, this design also has certain drawbacks. Because separate heat sink and antenna reflector designs are required, the number of components in the electronic device increases, and the overall size also grows accordingly. Furthermore, the need to procure materials for both designs separately increases material costs to some extent. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a directional antenna with a heat sink as a reflector, so as to solve the problems existing in the background art.

[0004] The directional antenna of this invention, which uses a heat sink as a reflector, is achieved through the following technical solution, including:

[0005] A metal reflector, on the back of which a PCB board is mounted;

[0006] The antenna body is mounted on the front of the metal reflector and passes through the metal reflector and is connected to the PCB board.

[0007] As a preferred technical solution, the PCB board serves as a carrier for electronic components and also functions as a heat dissipation device; chips are installed on the PCB board to realize circuit functions.

[0008] As a preferred technical solution, the metal reflector serves as the metal reflector of the antenna body, which is used to improve the directional radiation capability of the antenna body, and at the same time serves as a heat sink for the PCB board to dissipate heat for the chip.

[0009] As a preferred technical solution, a through hole is provided in the center of the metal reflector. The signal of the antenna body can be led out from the hole in the middle of the metal reflector 1. Under the action of the chip, the radio frequency signal is transmitted from the PCB board to the antenna body and finally radiated into the space. The antenna body can also be introduced from other positions through radio frequency lines.

[0010] As a preferred technical solution, a thermal pad is provided on the chip of the PCB board. The thermal pad is responsible for conducting the heat of the chip to the plane of the metal reflector, and then the heat is diffused into the air through the metal reflector.

[0011] As a preferred technical solution, the antenna body serves as the radiating unit of the wireless signal, and can be specifically implemented as a dipole, monopole, inverted-F antenna, or any other antenna form.

[0012] As a preferred technical solution, the metal reflector is made of aluminum or copper and has a thickness to meet the requirements of thermal conductivity.

[0013] As a preferred technical solution, the sides and top and bottom ends of the metal reflector can be designed in a bent or arc shape to enhance the directional radiation capability of the antenna.

[0014] As a preferred technical solution, the antenna body is designed with different antenna types and different antenna lengths to meet the requirements of different operating frequency bands.

[0015] As a preferred technical solution, the metal reflector, together with the shielding frame and conductive foam, can simultaneously achieve the function of electromagnetic shielding.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model integrates the antenna and heat dissipation functions by combining the metal reflector with the PCB board, thereby reducing the overall size and weight.

[0018] 2. The metal reflector of this utility model serves as a heat sink, which can effectively absorb and dissipate the heat generated by the chip, ensuring the stable operation of electronic components and extending the service life of the product. The metal reflector also improves the directional radiation capability of the antenna body, making the wireless signal more concentrated and improving communication efficiency.

[0019] 3. This utility model can adapt to different operating frequency bands by changing the type and length of the antenna body, thus enhancing the applicability of the product.

[0020] 4. The metal reflector of this utility model, in conjunction with the use of a shielding frame and conductive foam, achieves electromagnetic shielding, reduces electromagnetic interference, and improves the product's anti-interference capability. Attached Figure Description

[0027] like Figure 1 and Figure 2 As shown, the present invention provides a directional antenna with a heat sink as a reflector, comprising:

[0028] Metal reflector 1, with a PCB board 5 mounted on its back;

[0029] Antenna body 2 is mounted on the front of metal reflector 1 and passes through metal reflector 1 and is connected to PCB board 5.

[0030] The PCB board 5 serves as a carrier for electronic components and also functions as a heat sink. A chip 4 is mounted on the PCB board 5 to implement circuit functions.

[0031] Among them, the metal reflector 1 serves as the metal reflector 1 of the antenna body 2, which is used to improve the directional radiation capability of the antenna body 2, and at the same time serves as the heat sink of the PCB board 5 to dissipate heat for the chip 4.

[0032] Among them, the metal reflector 1 has a through hole in the center, and the signal of the antenna body 2 can be led out from the hole in the center of the metal reflector 11. Under the action of the chip 4, the radio frequency signal is transmitted from the PCB board 5 to the antenna body 2 and finally radiated into the space. In addition, the antenna body (2) can also introduce signals from a position on the metal reflector (1) different from the through hole through the radio frequency line.

[0033] The PCB board 5 has a heat-conducting pad 3 on the chip 4. The heat-conducting pad 3 is responsible for conducting the heat of the chip 4 to the plane of the metal reflector 1, and then diffusing it into the air through the metal reflector 1.

[0034] In addition, the antenna body 2 serves as a radiating unit for wireless signals, and its specific implementation can be, for example, a dipole antenna, a monopole antenna, or an inverted F antenna.

[0035] In addition, the material of the metal reflector (1) is a conductive metal, specifically aluminum or copper, and has a thickness to meet the requirements of thermal conductivity.

[0036] In addition, the sides and top and bottom ends of the metal reflector 1 can be designed in a bent or arc shape to enhance the directional radiation capability of the antenna.

[0037] In addition, the antenna body 2 is designed with different antenna types and different antenna lengths to meet the requirements of different operating frequency bands.

[0038] In addition, the metal reflector 1, together with the shielding frame and conductive foam, simultaneously achieves the function of electromagnetic shielding.

[0039] This invention integrates the antenna and heat dissipation functions by combining a metal reflector with a PCB board, thereby reducing the overall size and weight.

[0040] Metal reflectors, acting as heat sinks, can effectively absorb and dissipate the heat generated by the chip, ensuring the stable operation of electronic components and extending the product's lifespan.

[0041] The metal reflector enhances the directional radiation capability of the antenna body, making the wireless signal more concentrated and improving communication efficiency. By changing the type and length of the antenna body, it can adapt to different operating frequency bands, enhancing the product's applicability. The metal reflector, in conjunction with the shielding frame and conductive foam, achieves electromagnetic shielding, reduces electromagnetic interference, and improves the product's anti-interference capability.
