摘要
A novel dual-band antenna by using CRLH-TL structure is proposed for the wireless local area network (WLAN) application. The dual-band behavior is achieved by loading shorted meander lines and interdigital capacitor to form unit-cell CRLH-TL loaded antenna. The bandwidth enhancement of proposed antenna can be achieved by merging the two extended-bandwidth resonances. The dual-band version exhibits two distinct resonances at 2.4 GHz and 5.5 GHz, with measured -10 dB bandwidths of 500MHz and 2.1 GHz. The lowest resonance at 2.4 GHz corresponds to a 47% reduction in the resonant frequency compared to a reference unloaded monopole. The size of proposed antenna is 30 x 20 x 1.6mm(3). The measured gain reaches -1.6 dBi at 2.4 Hz and 2.6 dBi at 5.5 GHz, respectively. The measurement and simulation results show good agreement.
