Abstract

A compact antenna for ultra wide range applications is proposed using coplanar wave guide feeding. The dimensions of the proposed model are 25 x 25 x 1.6 mm3. The enhanced frequency range of 2.8-13.59 GHz is obtained as per return loss criterion by introducing the staircase model. The voltage wave standing ratio is less than 2 over the entire bandwidth. The resonant frequencies obtained are 3.2 GHz, 5.8 GHz, 9.7 GHz, and 12.6 GHz. In addition to the ultra wide band range of 3.1-10.6 GHz as per FCC regulations, the antenna is also operatable in X-band range and the partial range of Ku band from 12-13.59 GHz. The proffered antenna is suitable for applications of UWB like medical imaging, RADAR imaging, tracking, measurements and communications.
