A RFID+EAS CIRCUIT BOARD SIGNAL COIL

摘要

A kind of circuit board signal coils of labels is provided. The technical problem to be solved is that the described signal coils can issue ultra-strong induction signals, with the characteristics of no directional restriction and small volume, and can store article information, so that relevant applications can make analysis using the information. The technical solution is: A RTTD+EAS circuit board signal coil including a copper clad laminate (CCL) antenna, which is connected to the described LC resonator. The described CCL antenna consists of a CCL coil (10) and a chip (20) connected to the CCL coil. Two pairs of pins are led from the described CCL coil, of which the two symmetrical pins of one pair are electrically connected to Pin 1 and Pin 4 of the chip, and the two symmetrical pins of the other one pair are electrically connected to Pin 2 and Pin 3 of the chip.
