摘要: A passive wireless tag assembly comprises a plurality of antennas and transmission lines interconnected with circuitry constructed arranged in Van Atta array or configuration to reflect an interrogator signal the direction from whence it came. The may comprise at least one surface acoustic wave (SAW)-based circuit that functions as reflector is operatively connected information circuit. In another embodiment, delay and/or modulation circuit(s) are utilized. yet SAW-based devices mounted orthogonal surfaces corner reflector.
