A microstrip-fed printed monopole antenna having band-notch characteristics is proposed. The fullband antenna introduces 2.5-10.6GHz bandwidth covering the FCC frequency band for UWB applications. Six inverted L-shaped stubs on the bottom of the substrate, which are connected to the radiating patch through via pins, are used to create flexible multi-band filtering function. Using this technique it is possible to reject one to six different frequency bands.
