Description

Technical Field

[0001] The utility model relates to the technical field of 5G communication, in particular to an eight-port full-band high-gain wireless communication device. Background Technique

[0002] With the wide application of 5G communication technology, in some special industry application fields, the demand for multi-port full-band high-gain wireless communication devices is increasing day by day. Most of the previous wireless communication devices only had 3 to 4 ports, and the communication frequency band could only meet the 4G frequency band, unable to meet the performance requirements of the current 5G full band. 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 also necessary to take into account miniaturization of size and lower production costs. Therefore, it is very necessary to develop a wireless communication device that can meet the current 5G full band, has high gain, and can connect 8 ports at the same time.

[0003] The difficulty of the design lies in that it is difficult to meet multiple ports, the frequency band needs to cover the 5G full band (700 - 6000 MHz), and has a relatively high gain, and the size will become relatively large, making it difficult to adapt to the radio frequency part. To make the high-frequency part have relatively 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 eight-port full-band high-gain wireless communication device is proposed to solve the above-mentioned problems. Content of the Utility Model
