In this paper, a broadband rectangular microstrip patch antenna fed by coplanar waveguide feed with two slots in the ground plane is proposed. Investigations are carried out using coplanar waveguide feed with slotting in the ground plane to optimize the broadband operation. A sensitivity analysis shows the variation of return loss with different antenna parameters. This design of broadband antenna is obtained by properly choosing the suitable shape of slots in ground plane and selecting proper shape and size of the radiating patch. The designed antenna gives a return loss of -61dB and impedance bandwidth of 1.02GHz. The simulated results for return loss, bandwidth, VSWR and radiation pattern are studied.
