摘要：
A printed meander line antenna is described with a shaped ground plane and a back coupled rectangular patch. The prototype is proposed for wireless local-area network (WLAN) applications in the 2.4-2.48 GHz and 5.15-5.35 GHz frequency range. Dual-band operation, resonance impedance matching, and wide impedance bandwidth are the characteristics of the antenna. The antenna impedance matching for the first-resonance is provided by applying a shaped ground plane. The second even-mode resonance is generated by adding a rectangular patch at the back of the meander antenna. The impedance bandwidth for a return-loss less than -10 dB is 11% and 6% for the first- and the second-resonance, respectively. Furthermore,. the second-resonance frequency can be tuned by the length of the rectangular patch and it meets the requirements for the IEEE 802.11a WLAN (5.15-5.35 GHz and 5.470-5.725 GHz or 5.725-5.825 GHz). In fact, the second-resonance frequency can be continuously adjusted between 5.2 and 7 GHz with a little effect on the first-resonance.
