READ RANGE REDUCTION IN UHF RFID DUE TO ANTENNA DETUNING AND GAIN PENALTY

This article proposes an analytical study of the link budget in UHF RFID which takes into account the effects of materials where the tags ale adhered and which permits to analyze the impact of detuning and gain penalty on the lead lunge The analysis is performed for two typical tag antenna topologies a dipole antenna and a slot antenna (C) 2010 Wiley Periodicals Inc Microwave Opt Technol Lett 53 144-148 2011 View this article online at wileyonlinelibrary corn DOI 10 1002/mop 25625
