ABSTRACT An asymmetric coplanar waveguide fed frequency reconfigurable antenna based on composite right/left-handed transmission line is presented in this paper. The antenna is a composite right/left-handed transmission line composed of the meander line and a PIN diode. By controlling the switch of the PIN diode the antenna can change the frequency. Simulation and experimental results show that the −10 dB impedance bandwidth can change from 3.25–5.63 GHz to 2.73–2.96 GHz and 5.0–5.4 GHz. The antenna has good omnidirectional radiation in the working frequency band. The antenna can be widely used in WLAN and WiMAX.

采用CRLH-TL结构的非对称频率可重构紧凑型天线

摘要 本文提出了一种基于复合左手/右手传输线的非对称共面波导馈电频率可重构天线。天线是由曲折线和PIN二极管组成的复合左手/右手传输线。通过控制PIN二极管的开关,天线可以改变频率。仿真和实验结果表明,−10 dB 阻抗带宽可以从 3.25-5.63 GHz 变为 2.73-2.96 GHz 和 5.0-5.4 GHz。该天线在工作频段具有良好的全向辐射。该天线可广泛应用于WLAN和WiMAX。
