In this paper software based design and analysis has been carried out for a slotted circular patch antenna for dual band applications. A circular patch (radius 22 mm and thickness 0.5 mm) with cross slot etched at center provides dual band operation. The design is analyzed by Finite Element Method based HFSS EM Simulator Software. The designed antenna operates on ISM (Industrial, Scientific and Medical) band, UMTS (3G) and C-Band.
