Abstract:
In this paper an approach to improve the performance and bandwidth of square Microstrip antenna of frequency 2.4GHz is made by embedding the patch antenna with a modified square ring defects in the ground plane. The simulation process has been done through Finite Element Machine (FEM) based software High Frequency Structure Simulator (HFSS) software. The properties of the antenna designed for 2.4GHz lead to antenna virtual size miniaturization and better reflection coefficient with larger bandwidth and multi band operation. It is found that the antenna resonates at 1.625GHz for antenna-1 and 1.715GHz for antenna-2 with the band width of 1200MHz and the overall size reduction is found to be 39% in comparison with the conventional square antenna, and also its found that the because of the defected structure etched out of the ground plane the copper usage is reduced to 39%. Further it’s also observed that proposed antenna finds its most of application in the lower band like IEEE 802.11 and ISM Bands.
