Abstract

A compact Phi-shaped monopole antenna for super wideband applications is proposed. It consists of a Phi-shaped radiator derived from a conventional elliptical monopole and quarter elliptical CPW ground plane. An impedance bandwidth from 3.5 to 37.2 GHz is achieved with a ratio bandwidth of 10:1. It provides an average peak realized gain of 3.5 dB with a group delay of less than 0.5 ns. The proposed antenna structure provides large bandwidth with the advantage of miniaturized dimensions compared to other SWB antenna structures.
