Abstract
A dielectric-filled metal-patch antenna combinable with an internal RFID IC chip is introduced. This antenna is designed to operate either in an empty space or on top of large metal surface. The proposed tag antenna's dimension is adjusted to produce the maximum amount of scattered power due to tag's internal-impedance modulation for the normal incidence angle. A 2.44-GHz dual-patch antenna is fabricated to demonstrate the amounts of impedance-modulated scattered power at various reader-to-tag angles depending on the tag antenna radiation pattern.
