摘要

提出了具有谐振频率可重构能力的新型微带天线。天线由两个辐射矩形片组成,由中间带有PIN二极管的薄金属条连接。通过控制PIN二极管的偏置电压,天线可以在两个不同的频率之间切换。仿真和实验结果表明,在不增加任何匹配元件的情况下,所设计的天线在所有谐振频率下都具有很好的输入匹配性。

Switchable frequency bands microstrip antennas
Novel microstrip antennas with reconfigurable resonant frequency capability are proposed. The antennas consist of two radiating rectangular patches, connected by thin metallic strip incorporating a PIN diode in between. By controlling the PIN diode bias voltage, the antenna can be switched between two different frequencies. Both simulation and experimental results indicate that without any additional matching elements, the proposed antennas demonstrates very good input match at all the resonant frequencies.
