Abstract

An UHF RFID tag antenna which is comprised of a U-shaped tuning stub and a dipole radiator for different permittivity surfaces is investigated, fabricated and measured. For a conjugate match to the NXP G2XM chip impedance of 29-j137 at 915 MHz, a dipole tag antenna (91 mm × 10 mm) with U-shaped stub connected to dipole arms was designed. Simple size adjustments of the U-shaped tuning stub and dipole radiator of the antenna allow for easy control of the antenna resistance and inductive reactance, from which the chip impedance requirement may be readily satisfied.
