Comparitive Study of Feeding Techniques of Rectangular Microstrip Antenna for 2.4GHz RFID Applications Using IE3D

Investigating the Effects of Various Feeding Techniques on Rectangular Microstrip Antenna Performance for 2.4GHz RFID Applications

Abstract

This paper describes variety of feeding techniques applicable for rectangular microstrip antenna for 2.4GHz RFID applications. A proper impedance matching condition between the line and patch without any additional matching elements are used. After describing various feeding techniques, the paper gives a better understanding of the design parameters of an antenna and their effects on bandwidth return loss and gain. Finally simulation of antenna is done using design software IE3D and fabricated using in-house facilities.
