Description

ATTACHMENT THING OF RADIO FREQUENCY IDENTIFICATION FOR ELECTROMAGNETIC SHIELDING}

The present invention relates to a label tag attachment, the structure is designed to reduce the electromagnetic shielding between the RFID label tag and the metal material to increase the recognition distance of the label tag, and to reduce the manufacturing cost of the RFID label tag attachment.

In general, RFID (Radio Frequency IDentification) technology attaches an electronic tag to each target article, wirelessly recognizes a unique ID of the article, and collects, stores, processes, and tracks the information, thereby locating, remotely processing, and managing the article. And technology for providing a service such as information exchange between goods.

In general, an RFID system consists of an RFID tag or a transponder and an RFID reader or interrogator. When an article attached to an RFID tag is placed in a read zone of the RFID reader, the RFID reader sends an interrogation to the RFID tag, and the RFID tag responds to the reader's question. In a passive RFID system, an RFID reader modulates a continuous electromagnetic wave having a specific frequency to send an interrogating signal to the RFID tag, and the RFID tag reads its information stored in the internal memory. In order to transmit to the RFID reader, the RFID tag can be recognized by back-scattering modulation of electromagnetic waves transmitted from the RFID reader and sent back to the RFID reader.

The RFID tag is classified into a label tag and a metal tag. Since a label tag is always used to be attached to a specific item due to the nature of its use, an optimal design is required according to the characteristics of the tag's attached object and its operating environment. In particular, in the case of metal materials, unlike a label tag, which is commonly used, a dipole type antenna usually printed on thin paper or PET film is mainly used. When the dipole antenna is placed in parallel with the surface of the metal material, not only does not obtain enough power for driving the tag chip due to the boundary condition of the electromagnetic wave on the metal surface, but also due to the high conductivity of the metal material, By shorting the circuit, the potential difference for driving the RFID tag chip is hardly formed, and the RFID tag recognition distance becomes very short or unrecognizable. In order to solve this problem, a method of separating a distance between a metal material and a dipole antenna is used.

In other words, by inserting a shielding material such as rubber or Teflon between the metal material and the dipole antenna to space a certain distance, by appropriately selecting the dielectric constant of the insertion object can reduce the length of the dipole antenna, and also the electrical separation distance from the metal material Can be increased. However, the shielding material such as rubber or Teflon has a problem that the recognition distance is short because the shielding performance is not excellent, and above all, there is a problem that increases the manufacturing cost of the RFID tag.

On the other hand, the conventional metal tag uses a microstrip patch antenna or a PIPA (Planar Inverted Antenna) type antenna having a metal ground plane to attach to a metal material having high conductivity. For example, the RFID metal tag constituting the PIPA (Planar Inverted Antenna) type antenna requires a higher bandwidth of the antenna, so the recognition distance is shorter than that of the RFID label tag, and the manufacturing cost is high because the design itself is manufactured in consideration of metal attachment. Relatively high, there was a problem in printing and ID encoding difficulties. In addition, the conventional metal tag has a problem that the recognition distance is considerably shorter when attached to the non-metallic material because the design itself is attached to the metal material using the metal ground plane under the tag.

The present invention has been made to solve the problems of the prior art as described above, a label tag attachment having a simple structure by attaching a material that can reduce the manufacturing cost between the label tag and the target object, and can produce an electronic shielding effect The purpose is to provide.

In addition, an object of the present invention is to provide a label tag attachment to reduce the manufacturing cost and reduce the electromagnetic shielding effect by applying a different structure of the material to which the object is attached according to the metal or non-metal.

In order to achieve the object of the present invention as described above, and to perform the characteristic functions of the present invention described below, the characteristic configuration of the present invention is as follows.

According to an embodiment of the present invention, an RFID label tag attachment for electromagnetic shielding, comprising a target object to which the label tag is attached, and a material for increasing the air dielectric constant, and having a space of any size formed or folded Formed to form, the object is attached to one end (top), and the label tag attachment including an electronic shielding subsidiary material for attaching the label tag to the other end (bottom) is provided.

The subsidiary material is characterized in that made of a coated paper material.

In addition, when the sub-material is partitioned to form a space of the arbitrary size, the sub-material may be attached to one end of the metal material using a metal material as an object.

In addition, the height of the partitioned space is characterized by having a range of 1 to 2 cm.

In addition, when the subsidiary material is formed in the folded state, the subsidiary material may be attached to one end of the non-metallic material by using a nonmetallic material as a target object.

In addition, the auxiliary material may be a paper material of white art paper coated on both surfaces.

According to the present invention, a subsidiary material, which is a material of a paper of any size, is formed between a target object and a label tag, thereby increasing the air dielectric constant and causing an electromagnetic shielding effect, thereby causing a potential difference from the target object when a voltage is applied. The recognition distance of the label tag can be increased by deviating from the influence of the label tag.

In addition, according to the present invention, by using the subsidiary materials made of paper including any of the partitioned spaces as described above, the structural design is simple, and the effect of significantly lowering the manufacturing cost can be obtained.
