5G large-scale array electrically-tunable antenna

Abstract

The invention provides a 5G large-scale array electrically-tunable antenna. The 5G large-scale array electrically-tunable antenna comprises a radiation unit part, a power division feed network part, a reflecting plate part, a coupling calibration network part, a connector part, a phase shifter part and a transmission part, the phase shifter part comprises a movable part and a fixed part, and the transmission part is in power transmission connection with the movable part; the reflecting plate part is located between the power dividing feed network part and the coupling calibration network part, and the fixed part and the coupling calibration network part are both in signal connection with the power dividing feed network part; the radiation unit part comprises a plurality of dual-polarized radiation oscillators, and the dual-polarized radiation oscillators are fixedly connected with the power division feed network part; and a plurality of dual-polarization radiation oscillators form a sub-array, two dual-polarization channels are led out from each sub-array, and the dual-polarization channels and the coupling calibration network part are connected with the connector part. The antenna still has excellent amplitude consistency and phase consistency in a complex signal environment, and has the advantage of adjustable point downtilt angle.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a 5G large-scale array electrically adjustable antenna. Background technique [0002] With the continuous development of my country's mobile communication technology, the research on the fifth-generation mobile communication system (5G) has entered a substantive stage, and major operators have started 5G coverage pilots in some cities in China. As one of the key core technologies of the 5G mobile communication system, large-scale array antenna technology, the current system has higher and higher requirements for the overall antenna. It can even be said that the improvement and improvement of large-scale array antenna technology has become a key factor in 5G wireless communication. A crucial support point for development. [0003] The 5G large-scale array antenna has good 3D beamforming capabilities, which can achieve deep coverage in both horizontal and vert...
