摘要 设计了一种相位可调的极化可重构微带贴片天线。该天线采用双馈电方式工作,通过改变馈电网络中4个单刀双掷开关的导通状态在两个馈电点形成不同的相位差,从而实现左旋圆极化、右旋圆极化以及线极化之间的切换。实验结果与理论分析和仿真结果相吻合,天线实现了良好的极化重构能力。特别是不同极化状态下,天线工作频率具有良好的一致性。 A polarization reconfigurable microstrip patch antenna with tunable feeding phase is presented. The proposed antenna is excited by double feeds. Its feed network includes four RF single-pole double-throw(SPDT)switches. By controlling the states of SPDT switches, the phase difference between the two feed points can be changed, and the polarization sense of the antenna is switched between linear polarization, right-handed and left-handed circular polarization. The measured results of the antenna are consistent with theoretical analysis and the simulated results, and the reconfigurable capability of the antenna is demonstrated. Especially, the operating frequencies of the antenna have good consistency at each polarization sense.
