Bandwidth Enhancement by Corner Truncation in Rectangular Patch Antenna

Abstract

A method of improving operating bandwidth of a microstrip patch antenna by simply improving the structural shape, without affecting the size of an antenna is proposed in this paper. Simple calculations proved that Rectangular Microstrip Patch antenna of bandwidth 845.1 MHz can be efficiently transformed into microstrip patch antenna having bandwidth 9147.4 MHz . Two different approaches have been proposed and compared for better results.
