Design of a compact rectangular mono‐cone antenna for UWB applications

In this articel, we have designed, fabricated, and measured a compact rectangular mono-cone antenna for UWB applications. The measured bandwidth is 8.2 GHz from 2.8 GHz to 11 GHz for S11 < −10 dB. The path loss S11 and phase were measured and discussed. The radiation patterns and antenna gain across the frequency bands are also presented. From the measured results, the proposed antenna shows a good characteristic (almost linear phase, omni-directional pattern, and very low gain variation). © 2007 Wiley Periodicals, Inc.
