Design of a Reader Antenna for UHF RFID

Abstract:

Article Preview

A compact and circular polarized antenna for UHF band RFID handset reader was designed, and realized by cutting slits in the antenna patch and etching slots on the ground. Numerical simulation was performed for the characteristics of the antenna with the software HFSS 13.0.The simulation...

A Simple Uhf Rfid Circularly-Polarized Reader Antenna Design

In this paper, the simple antenna is proposed for ultra high- frequency (UHF) radio frequency identification (RFID) application. It is designed to achieve circular polarization with unidirectional beam. The antenna is composed of the truncated radiation patch and ground plane. The simulation results show that the antenna achieves the return loss of -31.92 dB, gain of 8 dBic, axial ratio (AR) of...
