Abstract
A novel radio frequency identification (RFID) tag antenna design mounted on metallic plane is presented in this article. The tag antenna structure is a rectangular radiating plate with a Z-shaped slot, which behaves like a dipole-type ground radiator. For a conjugate match to the Alien Higgs-4 chip impedance of 8–j148 Ω at 925 MHz is obtained by etched a Z-slot resonator in the center of the rectangular radiating plate (130 mm × 18 mm). By simply tuning the length and width of the Z-slot resonator, the tag antenna resistance and inductive reactance are easily adjusted to match the desired chip impedance. The half-wavelength resonant radiating plate (dipole type ground radiator) is spaced from the metallic plane and enhances the antenna gain by the reflection of the metallic plane.
