Title:
RFID SYSTEM, ARTICLE MANAGEMENT SYSTEM, HUMAN BODY DETECTION SYSTEM AND MOVING BODY DETECTION SYSTEM
Document Type and Number:
Japanese Patent JP2016040720
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve problems for example, in a conventional RFID system, due to interference of an electric wave, tag reading is not stabilized, tag information of an RF tag cannot be read out, or, when a person or article exists between a reader antenna and a place for placing a management object article, tag information of the RF tag cannot be read out similar to a case when there is a management object article, and a detection error of the management object article occurs, and the management regime of the article is not sufficient.SOLUTION: The RFID system of the invention comprises: a reader antenna 102a for transmitting and receiving a radio signal and formed of an open transmission line which is subjected to a match terminal; an RF tag 104 installed on a position where it couples with the reader antenna 102a by electromagnetic field coupling; and an RFID reader 103 connected to the reader antenna 102a.SELECTED DRAWING: Figure 1
