We analyzed micro strip antenna in IE3D by finite moment of method. In this paper we have compare and analyzed the micro strip antenna in infinite ground plane having dimension length, L = 700mil & width, W=800mil to the micro strip antenna in finite ground plane having dimension length, L = 1468mil & width, W=1568mil. The proposed antenna designs have been analyzed between 1GHz to 10 GHz. When the proposed antenna design on a 59mil GLASS PROXY Substrate of different dimension were examined for the same dielectric constant 4.3, loss tangent .019. At 5GHz the verify and Tested result on IE3D SIMULATOR for infinite ground plane are Return loss = -19dB, VSWR= 1.249. At 2GHz and 6GHz the verify and tested result on IE3D SIMULATOR for finite ground plane are Return loss = -11.81dB and -16dB, VSWR= 1.726 and 1.379. All results shown in Simulation results.

INTRODUCTION The area of microstrip antennas has seen some inventive work in recent years and is currently one of the most dynamic fields of antenna theory.This designing is very easy and chip in microstrip antenna designing.For simplity analysis and performance prediction, the patch is generally square, rectangular, circular, triangular, and elliptical or some other common. Among these the rectangular and circular patches are probably the most extensively used patches. As it is very easy to analyze a rectangular microstrip antenna. So in our paper we shall be designing a rectangular microstrip antenna. In this paper we have analyzed and tried to find out at which feed point in antenna will give better return loss. For our detected feed point, we have checked out all remaining parameters for it such as dB and phase of S parameter, real and imaginary part of Z, Smith chart and VSWR.
