Abstract

A printed microstrip-fed monopole ultra-wideband (UWB) antenna with triple notched bands is presented. By embedding a modified H-shaped resonator with an additional outer line beside the microstrip feedline, band-rejected filtering properties around the 3.5 GHz WiMAX band, the 5.2/5.8 GHz WLAN band, and the X-band satellite communication band are generated. The notched frequencies can be adjusted according to specification by altering the modified H-shaped resonator. Sharp gain reductions occur at 3.7, 5.2, 7.5, and 7.9 GHz. However, for other frequencies outside the notched bands, the gain is stable in the entire UWB band.
