摘要

In this paper, a novel coplanar waveguide (CPW) fed ultra wideband (UWB) antenna with reconfigurable functions and notch band characteristics is proposed for wireless communication applications. The proposed UWB antenna has two stop bands that are achieved by using the stepped impedance stub (SIS) loaded stepped impedance resonators (SIRs). The reconfigurable functions are obtained by means of two ideal switches that are implemented on the proposed two SIRs. By controlling the status of the ideal switches ON/OFF, the proposed antenna can work in UWB operation band with both switches OFF and the antenna can be used as a dual notch band UWB antenna when the status of both switches is ON. The frequency domain characteristics are investigated, and the time domain characteristics, such as group delay, have been studied in details as well. The simulation and experiment results demonstrate that the proposed reconfigurable antenna can well meet the requirement for the UWB communication, notch band UWB, and multiband communication.
