To prevent potential interferences from existing wireless systems including WiMAX and WLAN service, a triple band-notched ultra-wideband (UWB) antenna is presented. Firstly, the band-notches in WiMAX and WLAN bands are realized by inserting a quarter-wavelength open-ended slot in the radiating patch and adding half-wavelength C-shaped strips near the feed line respectively. Then a triple band-notched UWB antenna is presented by embedding a slot in the patch and adding strips near the feed line simultaneously. Due to weak coupling between band-rejected elements, we can finely modulate any notch band by altering the relevant element without influence on others. The simulation and measurement results show that the proposed triple band-notched UWB antenna achieves a wide bandwidth with band-rejected filtering properties in the WiMAX and WLAN bands. Analysis of the approach is illustrated to verify its advantage of notch-frequency independent tunability.
Keywords:Ultra-wideband (UWB) antenna; triple band-notched antenna; independent tunability
