This paper presents a circular shaped microstrip antenna through an inset feed. Simulation results show that the designed antenna can be used as a dual frequency antenna with effective return loss of -33.43 dB and -35.90 dB at 1.609GHz and 2.239GHz respectively. The dual band operation of the proposed antenna is due to two exited modes (TM01& TM11).for the proposed antenna TM11 is the fundamental as well as the dominant mode. The two modes have the similar broadside radiation characteristics and same polarization planes.
