NON-CONTACT DATA CARRIER WITH SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a self-transmission type non-contact data carrier with a sensor for preventing the plane dimension of an antenna for transmission from restricting the plane dimension of a circuit board without increasing any manufacturing process.

SOLUTION: Antenna wiring for transmission is formed with predetermined wiring length so as to be shaped like a stereoscopic coil alternately transmitted through the upper surface and lower surface of the circuit board, and extended horizontally to the surface of the circuit board by using a through-hole electrically connecting wiring on the upper surface and wiring on the lower surface of the circuit board.
