In this paper, a rectangular microstrip patch antenna is studied and the results are simulated using IE3D simulator at an operating frequency of 3 GHz. Microstrip Patch Antenna are low profile antennas, conformable to planar and non-planar surfaces, simple and easy to manufacture using modern printed circuit technology, mechanically robust when mounted on rigid surfaces, compatible with MIMC design and when the particular patch shape and size are selected; they are very versatile in terms of resonant frequency, polarization, pattern and impedance .IE3D is a Moment of Method Simulator which solves the Maxwell’s Equations in an integral form through the use of Green’s functions. The results are analyzed and discussed in terms of return loss, bandwidth, 3D radiation pattern, Efficiency vs. frequency plot, Total Field Directivity vs. Frequency Plot The return loss comes out to be -26 dB and bandwidth is 2.34% for the designed antenna. The length of the antenna is nearly half wavelength in the dielectric; it is a very critical parameter, which governs the resonant frequency of the antenna.
