A crown-shaped microstrip patch antenna for wireless communication systems

Abstract

This paper describes the design and analysis of a modified E-shaped and a crown-shaped microstrip patch antenna with excitation frequency of 1.2, GHz. Both the antennas are derived from a Rogers RT/Duroid 6202 laminate substrate (dielectric constant, =, 2.94 and loss tangent, =, 0.001). The simulation is achieved using the software Ansoft Nexxim. From the simulation results it is observed that the crown-shaped antenna exhibits 20.15, dB better return loss and 50% more gain than the modified E-shaped antenna. Furthermore, better impedance matching is observed for the crown-shaped antenna exhibiting that the crown-shaped antenna finds better applications than the modified E-shaped antenna to be effectively used for wireless application.
