Abstract

A COMPACT DEFECTED GROUND OCTAGONAL SHAPED PATCH ANTENNA FOR UWB APPLICATIONS

Darshan Sati,* Naval Kishor Chaudhary and Vijaya Bhandari

ABSTRACT

A compact defected ground octagonal shaped patch antenna is presented. The antenna uses duroid (?r= 2.2) as a substrate. The ultrawideband (UWB) range is covered using octagonal stub and rectangular slot. Octagonal stub is used for impedance matching. The stub and rectangular slot shows a good coupling in the entire UWB range. The designed antenna provides a wide bandwidth which ranges from 3.5 to 13.2 GHz (9.7 GHz) with VSWR less than 2. A thorough study of radiation characteristics of the antenna is presented. The proposed antenna has a small size of 22×24×1.6 mm3 while sustaining the UWB performance.
