Abstract: A wireless identification (RFID) tag, an electronic product PCB having same, and an electronic product management system using the RFID tag. The RFID tag includes an insulating means, a pair of upper terminals provided on the upper surface of the insulating means, a tag chip connected to the upper terminals, and a pair of lower terminals provided on the lower surface of the insulating means so as to face the upper terminals. The lower terminals are connected to first and second patterns of an electronic product PCB. When a radio wave radiated from a reader-writer is received in the first and second patterns, reactive coupling through an electric field is created between the upper and lower terminals, which are then electrically connected to the upper terminals. Since the pattern already formed in the PCB is used as an antenna, there is no need to form a dedicated antenna pattern.

Abstract: The present invention relates to printed circuit board (PCB) tracking technology, specifically to a dipole antenna structure for a radio frequency identification (RFID) tag. More specifically, the present invention relates to an edge type dipole antenna structure is implemented on an extremely small area on the edge of a ground plane provided on the PCB for various kinds of electronic products, and a PCB including the same.

Abstract: Disclosed is an RF transceiver in which transmission and reception are simultaneously performed, wherein a magnitude of a transmission leakage signal mixed into a receiving signal is measured, the maximum and minimum scopes on I/Q vector phase-plane in which an offset vector exists is set using the measured magnitude of the transmission leakage signal, the offset vector offsetting the transmission leakage signal as much as possible, a detection area in which the offset vector exists is determined in the set scope, and the offset vector is detected.

Abstract: A method for detecting offset signal corresponding to transmission leakage signal is disclosed, whereby reception sensitivity can be improved by accurately offsetting a leakage signal in transmission signal mixedly inputted into the reception signal in a radio transceiver, and an offset signal corresponding to a transmission leakage signal can be rapidly detected in the radio transceiver to rapidly offset the transmission leakage signal included in a reception signal.
