Constrained parameter analysis of Microstrip antenna

The advanced version of simple patch structure to multilayer configuration is microstrip antenna. The antenna designer has lots of challenges to use of antenna by modern military. Most of the communication channel easily synchronized with the low profile antenna. In this paper we evaluate the conspiring specification of microstrip antenna. the designing parameter of Microstrip patch antenna. At the resonating frequency 13GHz, we are determining the designing of rectangular patch antenna for the different material on the basis of dielectric constant. We are using the theory of Constantine bal an is for this purpose. In this, the dielectric constant is varying, and keeping some parameter constant like substrate thickness, microstrip transmission line, impedance and the resonating frequency. By varying the dielectric constant, we investigate the effect on width of microstrip transmission line, patch width, correct length needed the patch. Also In this paper the simulation of rectangular microstrip antenna is doing for finding the E and H plane pattern & radiation pattern by MATLAB code. MATLAB software is used for result simulation.
