Abstract: A compact rectangular monopole antenna fed by a tapered coplanar waveguide (CPW) with a band-notch function is proposed. A U-shaped slot is cut in the radiation patch to obtain the band-notch function and its parameters studied in detail. It is shown that the band-notched function can be realized by controlling location of the U-shaped slot. The notched band can be changed by adjusting the length and the width of the slot. Experimental results show that the proposed antenna has a stop-band of 5.07GHz to 5.85 GHz and a super- wideband characteristic, with impedance bandwidth reaching 15:1.
