Design and Comparison of Multi-coupling Mode's RFID Reader

LI Jun-feng

Abstract

Different transmit mode,frequency and distance between RFID reader and tag lies on different coupling modes.Currently,there are three coupling modes between reader and tag: dense coupling,inductive coupling and electromagnetic reverse scatter coupling.This paper mainly discusses the principle of three coupling modes,and schemes out the reader models of inductive coupling and electromagnetic reverse scatter coupling,and compares with them.
