Description

Technical Field

[0001] The present invention relates to the technical field of 5G antennas, and in particular to a large-array 5G antenna. Background Art

[0002] An antenna system composed of many identical single antennas (such as symmetrical antennas) arranged in a certain pattern is also called an antenna array. The independent unit of the antenna array is commonly called an array element or antenna unit. If the array elements are arranged in a straight line or a plane, it becomes a linear array or a plane array.

[0003] 5G network is the fifth generation of mobile communication network, with a peak theoretical transmission speed of up to 10Gb per second, which is hundreds of times faster than the transmission speed of 4G network. For example, a 1G ultra-high-definition movie can be downloaded within 3 seconds. The goal of 5G performance is high data rate, reduced latency, energy saving, reduced cost, increased system capacity and large-scale device connection. In the 5G mobile communication system, the antenna on the base station side uses large-scale antenna technology to improve system capacity. 5G large-scale array antenna has good 3D beamforming capability, which can achieve deep coverage in both horizontal and vertical directions, multiply the efficiency of spectrum resources, and form dynamic and targeted network coverage. In order to achieve this goal, 5G large-scale antennas should have more radiation units (≥64) and more RF transceiver channels (≥64) than conventional array antennas.
