A microstrip antenna consists of a radiating patch on one side of a dielectric substrate which has a ground plane on the other side. A 3X3 microstrip patch antenna which has width=w__ampersandsignlsquo; and length =l__ampersandsignlsquo; are placed over the surface of the substrate layer. The array of antennas exhibit dual polarization by using two feeds and hence called as orthogonal feeds. When the feed point lies on the diagonal then circular polarization occurs whereas if the feed point lies at any other place elliptical polarization occurs. In this paper we present the major parameters of the antenna as axial ratio, VSWR, radiation pattern, directivity and efficiency which are calculated practically.
