Comparative Study of Rectangular ,Circular and Corner Truncated Patch at 2.4 GHz

Abstract

This paper presents a comparative study of rectangular, circular and corner truncated rectangular patch at 2.4 GHz. Microstrip antenna offers linear or circular polarization. Three different patches are designed and their results are compared. This comparison helps in deciding the best shape of the patch which can be chosen for designing the antenna array for RFID reader[1]. HFSS simulation software is used to design patch and compute the various antenna parameters like return loss(S11), directive gain, VSWR, axial ratio etc.
