Description

Technical Field

[0001] This utility model relates to the field of antenna equipment technology, and in particular to a 5G broadband omnidirectional antenna. Background Technology

[0002] In mobile communication systems, antennas play a crucial role. The coverage of mobile communication networks requires antennas as carriers to transmit and receive the electromagnetic waves needed for network coverage. With the rapid development of wireless communication technology, the operating bandwidth of antennas is also one of the important factors that must be considered.

[0003] However, the current antenna gain of 6dBi at low frequencies and 8dBi at high frequencies is insufficient for current development needs. To solve the bandwidth problem, a circuit board plus stamped vibrator combination structure is needed to improve the subarray gain, thereby greatly improving the overall array gain. This allows the 5G broadband omnidirectional antenna gain to be significantly improved in coverage range of 9dBi at low frequencies and 12dBi at high frequencies, reducing the number of base stations and saving resources in various aspects. Therefore, it is very necessary to design a 5G broadband omnidirectional antenna. Utility Model Content

[0004] The main purpose of this invention is to provide a 5G broadband omnidirectional antenna, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A 5G broadband omnidirectional antenna includes a main support column. A four-in-one matching plate is fixedly connected to the lower left surface of the main support column, and a vibrator support column is fixedly connected to the upper surface of the main support column. A PCB printed matching plate is fixedly connected to the upper surface of the vibrator support column. There are four PCB printed matching plates, and the outer surfaces of the four PCB printed matching plates from left to right are sequentially soldered with a first copper vibrator, a third copper vibrator, a second copper vibrator, and a fourth copper vibrator.

[0007] In order to achieve the purpose of combining into a dual-frequency symmetrical vibrator, as the 5G broadband omnidirectional antenna of this utility model, the first copper vibrator includes a first high-frequency vibrator, and a first low-frequency vibrator is fixedly connected to the outer surface of the first high-frequency vibrator.

[0008] In order to achieve the purpose of combining into a dual-frequency symmetrical vibrator, as the 5G broadband omnidirectional antenna of this utility model, the second copper vibrator includes a second high-frequency vibrator, and a second low-frequency vibrator is fixedly connected to the outer surface of the second high-frequency vibrator.

[0009] In order to achieve the purpose of forming an antenna, as the 5G broadband omnidirectional antenna of this utility model, a coaxial cable is fixedly connected between the PCB printed matching and the main support column, and the coaxial cable is electrically connected to the four-in-one matching board.

[0010] In order to achieve the purpose of forming an array antenna composed of four subarrays, the number of coaxial cables in this utility model's 5G broadband omnidirectional antenna is adapted to the number of PCB printed circuits.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this utility model, through the arrangement of a main support column, a four-in-one matching plate, a vibrator support column, a PCB printed matching plate, a first copper vibrator, a third copper vibrator, a second copper vibrator, and a fourth copper vibrator, the main support column is connected and fixed to the PCB printed matching plate via the vibrator support column. The first copper vibrator and the second group of copper vibrators combine to form a dual-frequency symmetrical vibrator. The dual-frequency symmetrical vibrator mainly operates at a high frequency of 1710 to 2700 and a low frequency of 617 to 960. The third and fourth copper vibrators operate on the same principle. Then, through PCB printed matching, they are combined into a single unit. The main function of the PCB printing matching of the two units in a subarray is to combine the first and second copper resonators into a dual-frequency symmetrical resonator, and the third and fourth copper resonators into a dual-frequency symmetrical resonator. Then, they are combined and matched to a resistance value of about 50 ohms. Then, through the 50-ohm cable on the four-in-one matching board, the subarrays of the third, second and fourth copper resonators are combined into an array antenna, thereby improving the overall array gain. This increases the coverage range of the 5G broadband omnidirectional antenna in both low and high frequencies, reduces the number of base stations, and greatly saves resources in all aspects.

[0013] 2. In this utility model, by setting up a first high-frequency vibrator, a first low-frequency vibrator, a third copper vibrator, a second high-frequency vibrator, a second low-frequency vibrator, and a fourth copper vibrator, the first high-frequency vibrator and the second high-frequency vibrator mainly operate at high frequencies of 1710 to 2700, and the first low-frequency vibrator and the second low-frequency vibrator mainly operate at low frequencies of 617 to 960. The working principle of the third copper vibrator and the fourth copper vibrator is the same as above, thereby increasing the coverage range of the broadband omnidirectional antenna.
