Abstract :
A coplanar waveguide (CPW) fed ultrawideband (UWB) antenna with band-notched characteristic is proposed and implemented. By inserting a pair of coupling strips in the slot, a band-notched characteristic is realized. Adjusting the length, width of and the distance between the two coupling strips, a band-rejected filter characteristic at the wireless local area network (WLAN) band can be obtained. The fabricated antenna has a small size of 26 × 30 mm2. Good agreement is achieved between the simulated and tested results, which shows an ultra-wide impedance bandwidth from 3.1 to 10.6 GHz for VSWR <; 2 except a stop band for 5.15-5.825 GHz.
