In the recent years the development in communication systems requires the development of low cost, minimal weight, low profile antennas that are capable of maintaining high performance over a wide spectrum of frequencies. This technological trend has focused much effort on the design of a Microstrip patch antenna. A single feed compact Circular microstrip antenna is presented in this paper. L slits are introduced at the right edge of the patch to reduce the resonant frequency. For the proposed antenna resonant frequency obtained at 11.4 GHz with -38.2 dB return loss &. 21GHz Bandwidth which is suitable for X band application.
