Abstract
A radio frequency identification (RFID) system. An RFID tag may include multiple antennas connected with associated circuitry. An RFID tag's multiple antennas and associated circuitry are connected in parallel, and output power of the multiple associated circuitry can be combined. Each of the multiple antennas can be tuned for a different operating property or region. An RFID reader can include multiple antennas connected with associated circuitry. RFID reader's multiple antenna interfaces connect with a baseband processor, which can integrate resources of the reader's multiple antennas and associated circuitry. RFID tag and/or reader can be configured to support wireless channel diversity in enhancing at least one of power delivery and communication link budget.
