Design of Circular Patch Antenna Using L-Slit for WIMAX, WLAN & X-Band Applications
A single feed compact Circular micro strip antenna for dual band applications is presented in this paper. L slit is introduced at the right edge of the patch to reduce the resonant frequency. For the proposed antenna two resonant frequencies are obtained at 5.769 GHz and 9.74 GHz with bandwidth of 18.57 MHz, return loss - 15.35 dB and bandwidth of .74 GHz, return loss - 25.47 dB respectively. The antenna size has been reduced by 75.3 % when compared to a conventional microstrip patch. Mainly it is developed to operate in the WiMAX, WLAN & X-band application.
