Y-shaped Microstrip Patch Antenna

Abstract

This paper presents a design of Y-shaped patch microstrip antenna, which has been achieved by inserting Y-shaped strip in circular hole in square patch microstrip antenna and it has been excited by using microstrip line feed technique. Y-shaped microstrip patch antenna is designed on a FR4 substrate of thickness 1.524mm with relative permittivity of 4.4 and mounted above the ground plane. The measured return loss is -40.99dB at resonant frequency of 2.4GHz and obtained the maximum impedance bandwidth is up to 316MHz which is near about 13.17% are obtained with stable pattern characteristics. It is well applicable for wireless communication system.
