Bandwidth Enhancement of Microstrip Patch Antenna Using Parasitic Patch Configuration

Abstract

The author has simulated micro strip patch antenna with prime focus of increasing bandwidth using various techniques of probe feed, parasitic patch around the main patch and two layer of substrate. The simulation process has been done using HFSS (High Frequency Structural Simulator). In this paper, authors cover five aspects of micro strip antenna designs. The first is the analysis of single element narrowband rectangular micro strip antenna which operates at the central frequency of 2.4 GHz. The second/third aspect is the analysis and design of two gap/direct coupled parasitic patch along radiating edge of main patch and in forth/fifth aspect is the analysis and design of two layer of substrate on parasitic patch design. The properties of antenna such as bandwidth, S parameter, VSWR, Gain has been investigated and compared.
