Comparative Study of Microstrip Patch Antenna with Different Shapes and its Application

Abstract

Various advantages such as: easy to configure, low weight and low cost make microstrip patch antenna (MPA) the first choice for wireless communication system. The structure of the patch antenna consists of dielectric material in between radiating patch and ground plan. In this paper we present the comparative performance analysis of 4 different shaped antennas. The shapes taken into consider are E, T, H and F. The antenna is designed to operate at is 2.4 GHz. The results of different antenna parameters such as return loss VSWR, radiation pattern, gain and directivity are analyzed on different frequency bands. The E-shaped patch antenna is found much better than the others with overall gain of 7.2 dB at 2.4 GHz. Which is suitable for RFID reader application. Simulation is done using High Frequency Structure Simulator (HFSS) antenna simulation tool.
