Abstract
This paper presents a novel planar stepped fat monopole antenna for ultra wideband (UWB) applications. A drawback of a planar fat monopole antenna, relatively narrow bandwidth is overcome using stepped arms, and then UWB behavior of the antenna is obtained. For an easy feeding, a coplanar waveguide technique is used. For optimum design in terms of return losses and constant gain, the antenna is simulated with a commercial EM simulation tool. For verification, a prototype antenna is fabricated. From the numerical and measured results, the antenna has better than 10 dB return loss in the bandwidth between 2.2 GHz and 7 GHz.
