Abstract

The proposed antenna designed specifically for Cognitive radio applications consists of a circular monopole which is evolved into the Swastika shaped dotted monopole by incorporating slots into the plane circular monopole which enhances the band width as well as gain. This ultra-wideband sensing antenna covers the spectrum from 3.425 GHz - 14.99 GHz [11.53GHz] with a gain of 6.18dBi as against 10.56GHz bandwidth of plane circular monopole with a gain of 2.17dBi. Simulated results are presented and find in good agreement with the expected results.
