A MONOPOLE MICROSTRIP ANTENNA WITH ENHANCED DUAL BAND REJECTION FOR UWB APPLICATIONS

In this paper, a compact, planar ultrawideband (UWB) monopole microstrip antenna is proposed which ofiers dual band notch characteristics with enhanced rejection at frequency bands centered at 3.4GHz and 5.5GHz. To realize enhanced band notched characteristics at 3.4GHz, a pair of fllters is incorporated which includes an inverted 'L' shaped slot and a twisted 'J' shaped slot in the patch element. Another pair of fllters comprises of a spur line fllter in the feed line and 'U' shaped slot in the patch are used to get a strong frequency band rejection centered at 5.5GHz. Step by step development of the antenna with its analysis in frequency and time domain is presented. The prototype is fabricated and the measured results are presented which are in close similarity to the simulated results.
