In this paper, the authors present the new structure of truncated star shaped antenna with a Co-Planar Waveguide (CPW) feed as well as a Defected Ground Structure (DGS). This proposed antenna has been developed with the patch dimension of 18mm x 19.5mm. Copper has been preferred as the conducting material for patch and ground. The concept of truncation has been introduced in the proposed antenna. On truncating each peak side length of the star patch with the 3mm a wider bandwidth is achieved in the 2.2 - 6.3GHz range.
