Rectangular Microstrip Patch Antenna Design At 3 GHz Using Probe Feed

In this paper, a microstrip patch antenna is studied and the results are simulated using IE3D simulator with an operating frequency of 3 GHz. The conducting patch can take any shape but the preferred configurations are rectangular and circular since the other configurations are parameters. 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 and 2D radiation pattern, Gain vs. frequency plot. The return loss of this antenna is -26dB at 3GHz. The proposed antenna offers 2.34% bandwidth at 2.953.02 GHz. In designing a rectangular patch antenna, selection of patch width, length and dielectric constant are the major critical parameters.
