Band-notch characteristic has been of great interest recently to overcome the electromagnetic interference of Ultra-wideband systems (UWB) with other existing ones. In this paper, we present a novel microstrip-fed antenna with band rejection property appropriate for UWB applications. Band-notch characteristic has been achieved by adding a rectangular resonant element to the ground section. A pr...

─ A simple and compact microstrip-fed ultra wideband (UWB) slot antenna with dual band-notch characteristic for UWB applications has been presented. In order to increase the impedance bandwidth of the square slot antenna, we insert a T-shaped slot in the ground plane that with this structure UWB frequency range can be achieved. Additionally, by using a pair of Lshaped slits at the square radiat...
