DESIGN AND OPTIMIZATION OF HSHAPED MULTIBAND MICROSTRIP PATCH ANTENNA

Abstract

The design and optimization of rectangular patch antenna and comparison between H-shaped patch antenna and rectangular patch antenna have been investigated keeping in view of vital parameters such as S- parameters, VSWR, axial ratio, bandwidth & operating frequency. A novel approach is followed in the optimization process using FEM (Finite Element Method). This FEM technique gave more easy calculation in the design of Microstrip patch antenna and analysis of effect of various design parameters like dimensions (L & W) and substrate of antenna has been done. The proposed antenna is designed at 2.4 GHz of frequency and the simulation results a gain of 1.1016 with directivity of 2.2577 and bandwidth 307 MHz. The proposed ‘H’ shaped Microstrip antenna is fed by 50 Ω Microstrip feed line. The improvement in the results has been incorporated in the design.
