Abstract

As the notched bandwidth of the existing band-notched ultra-wideband（UWB） antennas are difficult to control,this paper presents a novel kind of UWB slot antenna with controllable notched bandwidth.In the investigation,first,a broadened rectangular solt antenna is used to generate ultra-wideband characteristics covering 3.1～10.6GHz band.Then,a pair of inverted L-shaped slits is embedded in the ground to create a band-notched function.The notched bandwidth can be easily controlled by adjusting the width and location of the slits.Finally,an UWB antenna with rejection band at 5.0～6.0GHz is successfully designed and fabricated,which effectively eliminates the potential interference from WLAN.

Key words： ultra-wideband antenna; notched characteristic; slot antenna; L-shaped slit; controllable notched bandwidth
