An active tagging system using circular polarization modulation

An active read/write microwave tagging system using circular polarization modulation as a novel modulation scheme for RFID systems to reduce demodulation complexity and power consumption on the battery powered tag is presented. Additional coding of the circular polarization modulated data reduces transmission errors due to polarization inversion at multipath propagation.
