BANDWIDTH ENHANCEMENT OF RECTANGULAR MONOPOLE ANTENNA USING MODIFIED SEMI-ELLIPTICAL GROUND PLANE AND SLOTS

摘要

This article presents an optimized design for a novel printed monopole antenna, with a notched semi-elliptical ground plane. A parametric study of the antenna parameters and their effects is given. The monopole antenna with the proposed bandwidth enhancement technique covers the band 3.1-10.6 GHz, which has been approved by the Federal Communications Commission as a commercial band for ultra-wideband communication systems, with a measured return loss bandwidth of 7.9 GHz (2.9-10.8 GHz).
