Abstract

The invention discloses an antenna sub-array, especially a sub-array for a 5G large-scale array antenna, comprising: N (N≥2) dual-polarized radiation units for transmitting or receiving the electromagnetic wave; a reflecting plate, It is used to reflect electromagnetic waves to improve the sensitivity of antenna signals; the feed network is arranged on the reflector and electrically connected to the radiation unit; the radiation unit includes a vibrator board and a balun bracket. Compared with the prior art, the antenna sub-array of the present application can share one radio frequency front end, reducing system cost and energy consumption.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, to an antenna subarray. Background technique [0002] Massive MIMO, a large-scale antenna array, is considered to be one of the core technologies of 5G. [0003] As one of the core features of the 5G antenna, the 5G large-scale antenna array provides the function of quickly scanning the coverage beam on the vertical and horizontal planes. [0004] Each antenna element of an ideal large-scale antenna array is connected to a complete RF front-end, including duplexers / switches, power amplifiers (PA), low-noise amplifiers (LNA), phase shifters, etc. Due to the presence of multiple RF front-ends, there are disadvantages such as high circuit complexity, difficult heat dissipation, complex calibration, and high cost. Contents of the invention [0005] In view of the above technical problems, the present application provides an antenna sub-array. A large-s...
