Compact microstrip fed UWB antenna with dual band notch characteristics

A compact microstrip fed ultra-wideband(UWB) antenna with dual band notched characteristics is presented. The antenna comprises of an elliptical UWB patch antenna with partial arc shaped ground plane fed by micro-strip transmission line. Two open-ended quarter-wavelength straight slots are etched in the patch to generate the two notched band. The UWB antenna covers a wide impedance bandwidth ranges from 2.86GHz-14.9Ghz with two band notched properties in the Wimax (3.1GHz-4.8GHz) X-band satellite link(9.6GHz-11.2GHz). The proposed antenna has a compact dimension of 32×38 mm

and nearby stable radiation patterns are obtained in the operating band.
