Abstract :
For passive RFID tags, one of the most important parameter is the read range. The power transferred to the tag IC and the tag read range are maximized when the reactance of the tag and IC chip are conjugate-matched. Structures effecting on antenna performance are studied in this paper that is based on the dipole antenna: Meander-line and tip-loading may reduce the size of UHF tag antenna. Shunt/Series inductors can increase antenna reactance. Large line-widths can improve the bandwidth of antenna.
