Abstract :
In this letter, a patch antenna with folded arrowhead-shaped structure is proposed to extend impedance bandwidth, decrease size and enhance gain. The antenna is optimized, fabricated and measured. The measured results indicate that an impedance bandwidth of 85% with Sll<;-10 dB (5.1 GHz to 12.6 GHz) is obtained and the antenna gain fluctuates from 4.4 dBi to 6.6 dBi over the whole bandwidth. The designed antenna is suitable for IEEE 802.11a, HiperLAN/2 and high band of UWB. Moreover, parametric studies are provided for antenna design.
