Compact planar antenna with dual band-notched characteristics for UWB applications

A compact planar monopole antenna with dual band-notch characteristics is proposed for ultrawideband (UWB) communication applications. The proposed compact antenna consists of an annular ring patch and a partial ground plane with a rectangular slot. Two partial and semicircular annular slots are etched at the upper and lower side of the ring radiator for achieving dual notched frequency band. The proposed antenna has two stop-bands of 3.2 to 3.6 GHz and 5.05 to 6.08 GHz while maintaining the wideband performance from 3 to more than 11 GHz. A symmetric radiation pattern and stable gain except in the notched band makes the proposed antenna suitable for being used in UWB applications.
