Description

Technical Field

[0001] The utility model relates to the technical field of 5G communication, and specifically relates to an all-band omnidirectional dual-port wireless device. Background Art

[0002] With the increasing application of 5G communication technology, most of the previous wireless communication devices can only meet the 3G and 4G frequency bands and cannot meet the current 5G all-band communication requirements. At the same time, as the 5G frequency increases, with the increase of distance, the attenuation of high-frequency signals will be more and more. To solve the problem of signal attenuation, the most direct and economical way is to increase the gain of the antenna. Therefore, it is also very important to increase the gain of the antenna in this solution. In addition, it is necessary to take into account the miniaturization of size and lower production cost. Therefore, it is very necessary to develop a wireless communication device that can meet the current 5G all-band, has high gain, and can simultaneously connect two ports.

[0003] The difficulty of the design lies in that the frequency band needs to cover the 5G all-band (700 - 6000 MHz), and has high gain, and the horizontal plane pattern meets omnidirectional, which will be relatively difficult, and the size will become relatively large. To make the high-frequency part have high gain and efficiency, usually expensive high-frequency plates are used as antenna units, resulting in very high costs and difficult to mass-produce.

[0004] Therefore, an all-band omnidirectional dual-port wireless device is proposed to solve the above-mentioned problems. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides an all-band omnidirectional dual-port wireless device, which includes two omnidirectional all-band antennas, and uses the method of metal structure plus parasitic unit to solve the above problems. It not only realizes frequency band expansion to cover the 5G all-band, but also meets the requirements of the MIMO multi-antenna system, improves the gain of the antenna, reduces the design difficulty and production cost, and can be mass-produced.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an all-band omnidirectional dual-port wireless device, which consists of 1 metal reflector and 2 antenna units, specifically the first antenna unit 1 and the second antenna unit 2. Each antenna meets the all-band and omnidirectional coverage in the horizontal plane. One SMA RF connector is welded on each antenna, corresponding to a total of 2 SMA RF connectors. 01 corresponds to the metal bottom plate, with a thickness of 1 mm and a material of aluminum. 02 corresponds to the metal reflector. 03 corresponds to 3 M3 nuts, and the metal reflector 02 is assembled and fixed with the metal bottom plate 01.

[0007] Further, the first antenna unit 1 is composed of five parts, including the first antenna unit body 11, the first metal nut 12, the first parasitic unit 13 in the shape of an arrow, the third metal nut 14, and the first SMA radio frequency connector 15. The first antenna unit body 11 is fixed on the metal reflector 02 through the first metal nut 12, the first parasitic unit 13 is fixed on the metal reflector 02 through the third metal nut 14, the flange part of the first SMA radio frequency connector 15 is fixed on the metal base plate 01, and the copper core of the first SMA radio frequency connector 15 is welded and fixed to the first antenna unit body 11.

[0008] Further, the second antenna unit 2 is composed of five parts, including the second antenna unit body 21, the second metal nut 22, the second parasitic unit 23 in the shape of an arrow, the fourth metal nut 24, and the second SMA radio frequency connector 25.
