Performance analysis of enhancing of fringing field of CPW fed rectangular patch antenna for wireless communication

摘要

This paper presents simulation of a multiband micro-strip antenna with a CPW feed to improve bandwidth and fringing properties like gain, directivity of the antenna for frequency range 10-70 GHz at simulation frequency 20 GHz. The various performance parameters are shown. The highest gain of 22.7 dB is obtained at 60.2GHz. The simulated model of antenna is ANSOFT HFSS 13.0. The comparative study of various structures is carried out to analyze the performance of antennas for better selection. The main objective is to enhance the performance of antenna parameter by making changes in the shape of patch.
