Abstract

A multi-function circular wide-slot antenna with small size is proposed and investigated for reconfigurable ultra-wideband (UWB) communication applications. The antenna can be used as a dual band-notched UWB antenna, a single band-notched UWB antenna, a UWB antenna, or even as a multi-band antenna. The band-notched characteristic is achieved by using a stepped impedance resonator (SIR) and an arc-shaped parasitic element (ASPE), while the multi-function design is realized by incorporating four switches into the SIR and ASPE. Simulation results demonstrate that the proposed antenna, with a wide impedance bandwidth and multi-function switchable properties, is suitable for UWB and cognitive radio communication applications.
