A compact open ended slot antenna with beveled shape rectangular patch for ultra wide band application

A compact open ended slot antenna with beveled shape asymmetrical rectangular patch for UWB application is proposed work in this paper. Multiple resonances are generated by using a beveled shape asymmetrical rectangular patch with the L-shaped open-ended slot structure which is fed by micro-strip line. Existing system has antenna size of 24.5×24.5mm
²
. In proposed system antenna size is reduced to 23.5×23.5mm
²
, achieves wide bandwidth from 3.2GHz to 12.3 GHz with -10 dB return loss.
