Problems solved by technology

[0004] When a large-scale array antenna is actually working, the coupling between the array elements always exists, which will have a very adverse effect on the performance of the antenna, making the antenna radiation unit designed according to the traditional method unable to meet the actual needs.

Abstract

The invention discloses a dual-polarization radiating unit and an array antenna provided with the dual-polarization radiating unit, the main technical problem to be solved is the problem of mutual coupling between arrays in the prior art. The dual-polarization radiating element includes a radiation device, which comprises array arms arranged symmetrically on a first PCB substrate, and the array arms are connected with a decoupling circuit by a direct feed mode or a coupling mode. The technical scheme that the effective length of the decoupling circuit is 0.02 to 0.1 wavelength solves the problem well and can be used for an array antenna.

Description

technical field [0001] The invention relates to a dual-polarization radiation unit and an array antenna with the dual-polarization radiation unit. Background technique [0002] With the development of the mobile Internet and the Internet of Things, the network speed, network capacity, number of terminal connections and air interface delay of the 4G mobile communication system can no longer meet the needs of the market and technology evolution. In the future, wider bandwidth, higher speed, and lower power consumption are required. 5G mobile communication technology with low latency and shorter delay will face huge challenges for base station antennas. Traditional base station antennas can no longer meet the needs of 5G systems. [0003] As one of the key technologies of 5G, large-scale antenna technology can well solve the shortcomings of 4G technology, by arranging dozens or hundreds of antenna arrays at the base station instead of just a few antennas , to radiate signals t...
