DESIGN OF OPEN SLOT ANTENNA FOR BANDWIDTH ENHANCEMENT WITH A RECTANGULAR STUB.

In this paper, a novel design of open slot antenna for bandwidth enhancement is proposed and investigated. The bandwidth enhancement of the proposed antenna is achieved by simply attaching a rectangular stub to the circular radiating patch. Experimental results indicate that the bandwidth of the antenna can achieve an operating bandwidth of about 139% over a wideband frequency range from 2.57 to 14.23GHz. This antenna has a small size of dimensions 20 x 35 mm² and is suitable for wideband applications in various wireless communication systems. [ABSTRACT FROM AUTHOR]
