摘要

5G提高能效的关键特征之一是适用于认知无线电技术。认知无线电具有感知操作态势并对感知结果作出一定响应的能力。电磁传播的运行情况使得天线的多径和去极化成为可能。为支持3.5 GHz 5G系统中的认知无线电技术，提出了一种极化可重构天线。该天线具有在线极化、右圆极化和左圆极化之间手动重新配置的能力，以减轻传播过程中的极化损失。结果表明，该天线在匹配阻抗和轴比方面具有良好的性能。仿真结果表明，轴比分别为1.762 dB和1.811 dB的RHCP和LHCP的S11小于-10 dB。而对于线极化，3.5 GHz时的S11大于-10 dB，且在3.1 GHz时轴比为40 dB时具有最佳值。

Polarization Reconfigurable Antenna for 5G Wireless Communication Systems On 3.5 GHz Frequency

One of the 5G key features in improving energy efficiency is suitable for cognitive radio technology. Cognitive radio has the ability in sensing the operation situation and providing a certain response regarding the sensing result. The operation situation of electromagnetic propagation allows multipath and depolarization of antenna due to many obstacles. In this paper, polarization reconfigurable antenna was proposed to support cognitive radio technology in 3.5 GHz 5G system. The antenna has capability for reconfigure between linear polarization, right-hand circular polarization (RHCP), and left-hand circular polarization (LHCP) manually to mitigate the polarization loss during propagation. The results show that antenna has good performance in the perspective of matching impedance and axial ratio. It is shown in simulation that the S11 less than -10 dB for RHCP and LHCP with axial ratio 1.762 dB and 1.811 dB respectively. Whereas for linear polarization, the S11 of 3.5 GHz more than -10 dB and has optimum value at 3.1 GHz with an axial ratio of 40 dB.
