An optimal antenna solution for UHF-RFID printer-encoder is discussed in this paper. Since, a printer-encoder antenna has to reliably communicate with only one targeted tag among a number of tightly spaced transponders in very close proximity, a numerical investigation is carried out in terms of spatial selectivity. Being the distance between the encoder antenna and the tags of a few millimeters only, antennas for UHF-RFID printer encoders are more similar to electromagnetic couplers and a specific analysis is required in terms of power transferred by the encoder to the transponder chip.

Abstract

An optimal antenna solution for UHF-RFID printer-encoder is discussed in this paper. Since, a printer-encoder antenna has to reliably communicate with only one targeted tag among a number of tightly spaced transponders in very close proximity, a numerical investigation is carried out in terms of spatial selectivity. Being the distance between the encoder antenna and the tags of a few millimeters only, antennas for UHF-RFID printer encoders are more similar to electromagnetic couplers and a specific analysis is required in terms of power transferred by the encoder to the transponder chip. A reader antenna identical to the tag antenna is proposed and a preliminary numerical investigation is here presented.
