Improvements in Band Rejection Characteristics
of a Wideband Antenna Using Resonant Slots

This article presents a method to improve and control the band rejection characteristics of wideband bow-tie patch antennas by using two notch slots. The two-pole band rejection characteristics were obtained by adjusting the mutual coupling values, as ...
In recent applications of telecommunications and remote sensing at microwave frequencies, the exploitation of UWB antennas is steadily growing. 1 UWB radio can use the frequency band from 3.1 to 10.6 GHz. UWB systems also need to be compatible with other already existing standards. 2 To allow such a...
