The growth of portable wireless communication devices has pushed designers to design miniature size antennas. The most prized among miniature antenna choices is the micro-strip patch antenna. These antennas have significant advantages such as low profile, light weight, relatively low manufacturing cost, and polarization diversity. This paper compares the performance of micro-strip patch antenna having different shapes of the patch (Square, Elliptical, Annular ring, Triangular) at a frequency of 2.43 GHz. To compare and analyze the performance, High Frequency Structure Simulator (HFSS) software was used. The results show that the size of the antenna will be smallest in case of square shape patch antenna followed by elliptical, triangular and annular ring. These results can be very useful while designing micro-strip patch antenna.
