RFID tag for metal the use of long range cognition

摘要

PURPOSE: a kind of RFID (radio frequency identification) label determines the system of the passive RFID chips of identification distance RFID IC (integrated circuit) by optimization minimum threshold voltage for remotely identifying that metal proposes identification distance. ;CONSTITUTION: a kind of H-type antenna radiation pattern (2) is incorporated in the RFID tag (10) of front surface and is formed in plate by circumferential surface for the metallurgy H-type antenna pattern, and center unit on the lower side includes (integrated chip) (3) RFID IC. Which is connected to antenna pattern to another antenna pattern, and covers the RFID tag.s that the rear surface of dielectric plate is formed on circumferential surface;The 2013 of copyright KIPO submissions
