은재질 인쇄패턴을 갖는 알에프아이디 태그{RFID tag with printed pattern of silver material} RFID tag with printed pattern of silver material

본 발명은 알에프아이디 태그에 관한 것으로, 보다 상세하게는 자동인식이 필요한 대상물의 모서리 부분 등에 손쉽게 부착할 수 있도록 태그 기판 자체를 유연성(Flexible)을 갖는 연질 합성수지재로 하고, 자동인식 대상물에 부착되는 RFID 태그의 안테나 패턴을 기존의 동(Cu) 박판이 아닌 은(Ag) 재질로 기판의 표면에 직접 인쇄(printing)하여 기판의 전, 후 양면에 RFID IC칩을 통해 상호 전기적으로 연결되는 제1, 제2 안테나를 설치함으로서 자동인식 대상물에 대한 각종 정보를 보다 정확하게 파악하여 인식의 오류를 최소화할 수 있는 은재질 인쇄패턴을 갖는 RFID 태그에 관한 것이다.The present invention relates to an RFID tag, and more particularly, a tag substrate itself is a flexible synthetic resin material having a flexible (flexible) so that it can be easily attached to an edge portion of an object requiring automatic recognition, and attached to an automatic recognition object. The first antenna pattern of the RFID tag is printed on the surface of the substrate by using Ag rather than the conventional copper sheet, and electrically connected to each other before and after the substrate through the RFID IC chip. In addition, the present invention relates to an RFID tag having a silver printing pattern capable of minimizing recognition errors by more accurately grasping various information on an automatic recognition object by installing a second antenna.

주지와 같이, RFID 태그는 IC 칩, 안테나 및 부착물로 이루어져 외부의 RFID 리더(Reader)와 소정의 데이터를 송, 수신하는 장치로서, 일명 트랜스폰더(transponder)라고도 한다.As is well known, an RFID tag is composed of an IC chip, an antenna, and an attachment, and is a device for transmitting and receiving an external RFID reader and predetermined data, also called a transponder.

이와 같은 RFID 태그는 비접촉 방식으로 RFID 리더와 데이터를 송, 수신하게 되는데, 채용되는 주파수의 고저에 따라 유도성 결합(Inductive Coupling), 전 자기 역산란 결합(Back scattering), 표면 음향파(SAW: Surface Acoustic Wave) 등을 이용할 수 있으며, 상기 전자파를 이용한 전이중 방식(FDX: Full Duplex), 반이중 방식(HDX: Half Duplex), 및 순차적 방식(SEQ: Sequential)으로 RFID 리더와 데이터를 송, 수신할 수가 있다.The RFID tag transmits and receives data to and from the RFID reader in a non-contact manner. Inductive coupling, back scattering, and surface acoustic waves (SAW) are applied depending on the height of the frequency employed. Surface Acoustic Wave) and the like, and are capable of transmitting and receiving RFID readers and data in full duplex (FDX), half duplex (HDX), and sequential (SEQ) modes. There is a number.

예로서, RFID 태그는 비접촉 방식이라는 특성상 물품의 관리 또는 통화 결제를 위한 IC 카드나 통행권 등 다양한 용도로 사용되고 있으며, 별도의 내장 배터리 없이 외부 변화에 수동으로 작동하여 필요한 전류를 생성하는 패시브형 태그(Passive Tag)가 주로 사용된다. For example, RFID tags are used for various purposes such as IC cards or pass tickets for the management of goods or payment of calls due to the nature of non-contact, and passive tags that generate the required current by manually operating on external changes without a separate internal battery ( Passive Tag) is mainly used.

또한 데이터의 수정가능 여부에 따라 Read-Only, WORM(Write Once Read Memory), Read/Write 방식 등으로도 구분된다. In addition, depending on whether the data can be modified, it is also classified into read-only, write once read memory (WORM), and read / write methods.

RFID 리더는 RFID 태그와 무선신호를 송, 수신하여 RFID 태그에 내장된 데이터를 리드/라이트하는 역할을 수행한다.The RFID reader transmits and receives an RFID tag and a radio signal to read / write data embedded in the RFID tag.

그리고, 종래의 RFID 기술을 이용한 인식 방법으로는 태그 자체를 사용하는 방법, 라미네이팅(Laminating)에 의해 제작된 카드에 일체화 시키는 방법, 스티커와 같은 접착 매개체를 이용한 방법 및 인젝션 몰딩(Injection Molding)을 통해 태그를 일체로 성형 화하는 방법 등이 있다. In addition, as a recognition method using a conventional RFID technology, a method using a tag itself, a method of integrating into a card manufactured by laminating, a method using an adhesive medium such as a sticker, and injection molding And a method of integrally forming a tag.
