| 摘 要： | 设计了一种左/右旋圆极化可重构的微带天线。在矩形微带贴片的两条边上增加枝节，贴片与枝节通过PIN 二极管开关连接，通过控制PIN 二极管的通断来改变正交模式的相位差，使天线在同一个馈电点上可实现左旋圆极化（LHCP）和右旋圆极化（RHCP）的重构。该天线在（2800±10）MHz 的频率范围内驻波比小于2，轴比小于3dB。仿真结果与测试结果均验证了该方案的可行性。

| Abstract: | In this paper, a microstrip patch antenna is proposed to achieve circular polarization diversity. Stubs are addedaround two sides of the rectangle patch and connected by PIN diodes. By turning the diodes on and off, the phase difference of twoorthogonal modes is changed, which lead to the novel antenna can radiate with either left hand circular polarization (LHCP) orright hand circular polarization (RHCP) using the same feeding probe. The voltage standing wave ratio (VSWR) and axial ratio(AR) values are less than 2 and 3dB respectively in (2800±10)MHz frequency range. The simulated and measured results bothvalidate the proposed design process. |
