摘要

A very compact microstrip fed triple band notched (Ultra Wide Band)UWB antenna is presented here. The antenna uses open ended quarter wavelength slot in the patch for rejecting 3.5 GHz (WiMAX) and a half wavelength slot in patch and ground respectively for rejecting 5.5 GHz (WLAN) and 8.2 GHz(ITU ‘X’ downlink band)respectively. While embedding the whole three rejection bands design to the compact UWB antenna, the main problem faced was the cross coupling between the bands. The simulated VSWR results and radiation pattern shows that due to the optimum spacing provided between the rejection band design the resultant triple band notched antenna operates fairly at required MUWB frequencies without interferences from co-existing bands. The size of this antenna is 14∗22∗1.6 mm which is very compact. The fractional bandwidth of the proposed antenna is 125%. Good Voltage Standing Ratio (VSWR) and radiation pattern are also obtained in the required UWB band. The compact size of antenna makes it a suitable candidate for Wireless Personal Area Network Applications (WPAN).
