%X 本文提出一种用于5G通信的圆极化微带相控阵列天线。首先，提出并设计了一款双馈点的圆极化微带天线单元，在无限周期阵中的仿真结果表明，该阵列单元在两个主平面实现 ± 30度的扫描，在3.4~3.7 GHz频段内的反射系数S11 &lt; ？10和轴比AR &lt; 3.5 dB。最后，设计了一款7 × 7圆极化微带阵列天线，仿真结果表明，该阵列天线工作在3.4~3.7 GHz频段，在扫描范围内的轴比均小于3 dB，且在扫描范围内增益变化平稳，实现了良好的圆极化扫描特性。<br />
This article proposes a circularly polarized microstrip phased array antenna for 5G communication. Firstly, a doubly-fed circularly polarized microstrip antenna unit was proposed and designed. Sim-ulation results in an infinite periodic array showed that the array unit achieved ± 30 degree scan-ning on two main planes, with a reflection coefficient of S11 &lt; ？10 dB and the axial ratio of AR &lt; 3.5 dB in the 3.4~3.7 GHz frequency band. Finally, a 7 × 7 microstrip array antenna was designed, and the simulation results showed that the array antenna operated in the 3.4~3.7 GHz frequency band. The axial ratio within the scanning range is less than 3dB, and the gain changes smoothly within the scanning range, achieving good circularly polarized scanning characteristics.
