Abstract

In the 5th generation mobile communication system (5G), there is a strong demand for higher speed and higher capacity. The beamforming technique using phased-array antennas is effective for long-distance radio propagation and for reducing interference signals in the high SHF (super high frequency) band because the phase shift of the antenna array elements can be controlled to produce a narrow-band beam and to control the directivity. We have developed the 28 GHz array antenna for small cells and evaluated the beamforming characteristics using an RF analog phase shifter control scheme. In this paper, we verify the computer simulation and evaluation results of the beamforming characteristics of a newly developed 4×4 phased array antenna.
基于RF电路相位控制的4×4单元组态28GHz SHF波束形成仿真与评价
在第五代移动通信系统(5G)中,对更高的速度和更高的容量有强烈的需求。利用相控阵天线的波束形成技术可以控制天线阵元的相移产生窄带波束并控制其指向性,因此可以有效地实现无线电的远距离传播和在超高频(SHF)波段减少干扰信号。我们开发了用于小型小区的28ghz阵列天线,并使用射频模拟移相器控制方案评估了波束形成特性。本文对新研制的4×4相控阵天线的波束形成特性进行了计算机仿真和评估。
