ON THE READ ZONE ANALYSIS OF RADIO FREQUENCY IDENTIFICATION SYSTEMS WITH TRANSPONDERS ORIENTED IN ARBITRARY DIRECTIONS
Abstract
One of the most important characteristics of a Radio frequency identification (RFID) system is its "read zone", which is defined as the volume inside which the base station can communicate with the transponders (or, tags). This paper presents a systematic approach to analyzing the read zone of an RFID system where the base station antennas are a pair of switchable circularly polarized antennas and the transponder antennas are linearly-polarized and oriented in arbitrary directions.
