A compact rectangular monopole antenna fed by a tapered coplanar waveguide (CPW) with a band‐notch function is proposed for super‐wideband (SWB) applications. A U‐shaped slot is cut in the radiation patch to obtain the band‐notch function and its parameters are studied in detail. It is shown that the band‐notched function can be realized by controlling the location of the U‐shaped slot and the notched band can be changed by adjusting the length and the width of the slot. Experimental results demonstrate that the proposed antenna has a stop‐band of 5.07–5.85 GHz and a super‐wideband from 0.595 to 8.95 GHz (15:1) for VSWR ≤2. © 2007 Wiley Periodicals, Inc.
