Inductively Coupled Loop Antenna Design for UHF RFID On-Body Applications
In this paper, the authors present a one-wavelength loop antenna fed by an inductively coupled loop for on-body applications. An equivalent circuit for the inductively coupled loop antenna is proposed to synthesize the antenna system with a microchip. The designed tag is printed on a PVC substrate and placed close to a four-layer stratified elliptical cylinder human model. The card-type tag measures 85.5x54x0.76mm3 and is suitable for use on a student ID card for a broad range of applications.
