Design and Implementation of a Compact CPW-Fed UWB Monopole Antenna

Abstract

In this paper, a compact ultra-wideband patch antenna is presented and discussed. The antenna, printed on Rogers RT5580, consists of leaf-shaped radiating element excited through tapered coplanar waveguide feed line, and semi-elliptical partial ground plane. It covers a frequency range starting from 2.8 to 15.1 GHz. The antenna prototype is fabricated, and a good agreement is obtained between the experimental and simulation results indicating that the proposed structure, having a reasonably compact size of 20x32 mm2 is suitable for a wide variety of applications due to its large operating frequency.
