摘要

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.
