Abstract

Multi-polarization of a flower shaped Microstrip antenna sub array with directivity and gain enhancement for radar application in S band is explained here. Sub array consists of planar side flower shaped five Microstrip patch antennas with a dual fed element feeding the outer patches through a straightforward network of resonant Micro strip lines. The central Patch is excited by a pair of coaxial-probes fed for Circular polarization. By properly exciting the sub array, any kind of polarization of the radiated field can be obtained. Preliminary numerical results obtained by using finite element method (FEM) as a method of analysis are shown.
