Abstract

The new antenna, described here, can be reconfigured to operate efficiently over a total 7 dB return loss bandwidth from 460 MHz to in excess of 12 GHz. The antenna is based around a CPW-fed monopole featuring an elliptical base. Reconfiguration is achieved by switching the ground plane shape between convex and concave. The use of a concave ground plane, improves the impedance match throughout the low frequency band (i.e.below 1.44GHz), whilst use of a convex ground plane improves the impedance match within the high frequency band (i.e. above 1.44GHz).
