A circular shaped CPW fed capacitive coupled monopole antenna is presented. Ground dimensions of the CPW feed are used to tune the proposed antenna's input impedance (bandwidth). Also, these dimensions (ground) can be used to work antenna either in ultra wideband or multiband mode. The capacitive gap introduced on the circular stub will also decide the working of antenna as either wideband or multiband operation. Placement of capacitive gap may be at any point on the circular stub. In this paper, the authors investigated its effect at three different places i.e., lower end, at the center, and at the upper end of the geometry.
