    摘要： A passive phase jitter modulation (PJM) tag is charged with power in a continuous wave (CW) section. When receiving a command from a reader, the passive PJM tag must recognize the command and determine exactly when to begin demodulating the command. Only then can the passive PJM tag demodulate the command. To this end, a synchronization apparatus for accurately demodulating a signal input to a PJM tag includes a plurality of correlators correlating a received phase jitter-modulated signal with a template of an internal matched filter which is in the same form as at least a portion of a modified frequency modulation (MFM) flag.

    摘要： An antenna includes a polyhedral dielectric material, a feed loop, a polygonal radiating patch, and shorting plates. The feed loop is electrically connected with a radio frequency identification (RFID) tag chip for supplying power to the RFID tag chip. The polygonal radiating patch is magnetically coupled with the feed loop for radiating the electromagnetic waves. Each of the shorting plates disconnects the radiating patch and a ground surface and controls the magnetic coupling of the radiating patch and the feed loop. Accordingly, an RFID tag that can be attached to a metal material is provided.
