Abstract:

A smart reflection antenna system and method are disclosed. In this regard, a representative embodiment of a smart reflection antenna system includes an interrogator transmitter (IT) having an IT array of at least two antennas, the IT being configured to simultaneously transmit a carrier signal from multiple antennas of the IT array. The system also includes a tag having a tag array of at least one antenna. The tag being configured to simultaneously receive the carrier signal from the IT array via the tag array, modulate the carrier signal into a modulated carrier signal; and simultaneously transmit the modulated carrier signal via the tag array. The system also includes an interrogator receiver (IR) having an IR array of at least two antennas, the IR being configured to simultaneously receive the modulated carrier signal from the tag array via multiple antennas of the IR array. Other embodiments of systems and methods are disclosed.
