As several conventional shapes of microstrip antennas are presented and analyzed by many researchers which give us a clear view about the basic characteristics of MSA and leads toward designing different patch shapes to enhance the performance of MSA for different applications. In this paper a rectangular microstrip patch antenna is considered having a semi ring slot on the patch using IE3D simulation software and the results regarding antenna performance is obtained by the simulation. The simulation of the designed antenna structure shows the effectiveness of the antenna in terms of bandwidth, gain, directivity. The result analysis shows that the designed antenna structure is suitable for two different frequency bands (1.9 GHz and 2.7 GHz) with a bandwidth of 09.43% and 13.68% which makes this antenna structure suitable for two different types of applications. The directional capabilities i.e. gain and directivity of the designed antenna is also good which provides a maximum gain of 4.67dBi and maximum directivity of 5.39 dBi at 2.87GHz.
