Label of wireless radio-frequency identifying system

Abstract

The tag of radio frequency ID system (RFID TAG) includes dielectric substance base plate attached to antenna body made from electroconductive material, and IC connected to antenna body electrically. The antenna body possesses radiation part and grounded part. The radiation part is formed on one face of dielectric substance base plate, and the grounded part is formed on the other face of dielectric substance base plate. Integral composition of antenna reaches generation of resonance mode or mechanism of radiation, as well as makes both of radiation part and grounded part connect to IC electrically. Integral structure promotes reads data from or writes data to corresponding reader-writer by using RFID TAG.

Description

technical field [0001] The invention relates to a radio frequency identification system tag (RFID TAG), in particular to a special structural design of an antenna body, and further constitutes a radio frequency identification system tag that can be used corresponding to metal. Background technique [0002] The tag (TAG) of the radio frequency identification system (Radio Frequency Identification, referred to as RFID) refers to the general term for the components composed of IC and antenna. As long as it is equipped with a dedicated reader / writer (READER / WRITER), it can be read or written from the outside. Due to the characteristics of the RFID system, it is able to quickly detect the attributes of the items and other information wirelessly, and the enterprise users can accurately grasp the movement of the items and achieve the efficiency of the logistics. Therefore, it is gradually replacing the traditional The trend of commodity bar code and magnetic card. [0003] General...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problems and deficiencies that the above-mentioned existing commonly used RFID TAG is attached to a metal object, information cannot be transmitted with the reader, and the isolation pad method that does not fundamentally solve the problem relatively increases the volume and cost of the RFID TAG, the present invention The purpose is to provide a radio frequency identification system label that is more ideal and practical, can fundamentally solve the problem of metal surface application, and has a more complete effect.

[0006] The present invention does not need to use isolation pads to isolate the RFID TAG from the metal surface, and does not need to add additional components on the dielectric substrate to solve the problem of metal interference with radio waves. Under the condition of no isolation components, it is more helpful To achieve the purpose of information transmission with the reader, the overall has the practical effect of simple structure, no need to increase the volume and reduce the manufacturing cost
