We have investigated a unique design of microstrip antenna with dual band. The designed antenna constitutes of two C-shaped slots on patch. The C-shaped slots are arranged such that they form the mirror image of each other. The spacing between the two slots is chosen of 0.1cm. The proposed design reports a dual band with resonating frequency lying in ultra wideband region. The optimum gain reported for designed antenna is 6.1869dB. The return loss observed for antenna is-24.0982dB. Besides we have investigated VSWR which reports to be 1.0852.
