Abstract
A compact reconfigurable band-notched UWB antenna is presented in this paper. The antenna has a partial ground plane with a rectangular slot to achieve the desired bandwidth for UWB from 3.1GHz to 12GHz. The antenna has a single band-notch frequency which is achieved using a switched U-shaped slot, inserted in the radiating patch. This slot is used to decrease interference with WIMAX applications from 3.3GHz to 3.9GHz. The switching reconfiguration of the proposed antenna is achieved through two ideal switches. The antenna inhibits two modes of operation, which result from controlling the switch on/off. The proposed antenna has VSWR < 2, except the WIMAX band, as desirable. The proposed antenna design has been fabricated and tested. Measurement results show very good agreement with simulation results.
