The circular slot antenna is designed for C-band (4-8GHz) is suitable for mobile applications center frequency at 5GHz. It contains 12 semicircular iteration sections each section is 1mm wide produce fringing effect. The proposed antenna has a compact size, good radiation characteristics and wide band-width of 4.6GHz to satisfy the requirement of the current wireless communication systems. Antenna parameters like return loss (S11), gain, VSWR and radiation pattern are calculated and simulated and compared. The design and simulation is done using HFSS v13 simulation tool and it is fabricated on a FR4 epoxy and RT duroid 5880 dielectric substrate.
