Microstrip patch antennas have been widely used in a various useful applications, due to their low weight and low profile, conformability, easy and cheap realization. In this paper, bandwidth of microstrip antenna is increased by introducing a slot of a shape and using stacked configuration. The antenna is fed by coaxial probe feeding technique. The designed antenna provides the bandwidth of 220MHz (3.86GHz-4.08GHz) with return loss of -30.71db at 3.97GHz and 1.87 GHZ (9.8GHz- 11.67GHz) with return loss of -23.02db at 10.02GHz.
