A printed ellipse‐shaped monopole antenna with coplanar waveguide feed for use in ultrawideband (UWB) communication systems is presented.In this proposed antenna, the impedance bandwidth increases with a pair of ellipse‐shape‐combined design on the patch and ground plane. The effect of the ground plane form on the optimization of the S 11 characteristics is discussed in detail. Proposed antenna operates in the adopted bandwidth (3.1–10.6 GHz) with S 11 < −10 dB and covers it very well from 2.4 to 20 GHz. Experimental and simulated antenna results show that the proposed antenna has a desirable S 11 level and radiation pattern characteristics for the UWB frequency band range. © 2012 Wiley Periodicals, Inc.
