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.
