Description

Radio frequency identification tag with reinforcing structure

This creation is related to RFID tags, especially a radio frequency identification tag with a reinforced structure.

Radio Frequency Identification (RFID) is a communication technology mainly composed of wireless information processing technology, readers, and RFID tags. The RFID can be applied in a wide range of applications such as inventory and logistics management, asset management, library management, access control, commodity security, automotive chip security, etc. as identification and tracking applications.

As shown in FIG. 1 , there is a conventional RFID tag 10 which is mainly composed of a chip 12 and an antenna 13 electrically connected to the chip 12 on a body 11 . The RFID tag 10 is only provided with a dedicated read. The writer can read or write data from the outside in a non-contact communication manner, and at the same time, the reader can retrieve and recognize the information of the RFID tag 10 to provide further processing, use or added value to the application system of the back end. However, the RFID tag 10 still has defects that must be improved immediately in actual use:

First, when the RFID tag 10 is placed on a soft material, such as a work clothes, a hood, a hat, a work shoe, etc., the body 11 is made of a soft material (for example, rubber) because of the specific flexibility required for wearing or washing. Encapsulated, however, since the wafer 12 and the antenna 13 are encapsulated by the body 11 to form an extremely thin and equal thickness sheet, the RFID tag 10 When used in the aforementioned setting state, the body 11 is easily bent, so that the antenna 13 or the wafer 12 provided in the body 11 is deformed in synchronization, and the long-term and repeated bending will cause the RFID tag 10 to be damaged and unusable. Most of the reasons for this are the disconnection of the electrical connection A between the wafer 12 and the antenna 13. In other words, since the body 11 has no protective structure design corresponding to the electrical connection A between the wafer 12 and the antenna 13, the structure of the body 11 is insufficient in strength and is easily damaged by the stress of repeated bending.

Secondly, since the surface 111 of the body 11 of the RFID tag 10 is a flat surface, when used for directly attaching to; or being close to the human body; or being close to a moisture-rich surface, the reader device may be caused. The emitted electric wave is easily absorbed by the human body or moisture, causing difficulty for the reader to read the RFID tag 10. In particular, the RFID tag 10 has an operating frequency above the UHF.

Therefore, how to develop an RFID tag that can solve the aforementioned drawbacks, that is, the motive for the creation of the case.

The purpose of the present invention is to provide a radio frequency identification tag with a reinforcing structure, which mainly has a reinforcing portion on the body of the RFID tag, and the reinforcing portion corresponds to an electrical connection between the chip and the antenna, thereby improving the structure of the body. The strength is to reduce the disconnection of the electrical connection between the wafer and the antenna, and increase the service life of the RFID tag.

Another object of the present invention is to provide a radio frequency identification tag having a reinforcing structure, which mainly has a reinforcing portion or a spacer protruding from the body of the RFID tag, thereby reducing the application of the RFID tag to the human body or the water-rich The impact on the surface. Or forming a dielectric space with the surface of the object to be attached to improve the accuracy of the reader reading the RFID tag.

In order to achieve the foregoing objective, a radio frequency identification tag having a reinforcing structure according to the present invention includes: a body having a first surface and a second surface opposite to the first surface; a wafer, Provided in the body, and having a plurality of chip electrical connection portions; an antenna disposed in the body and having an antenna electrical connection portion electrically connected to each of the chip electrical connection portions; at least one reinforcing portion, convex Provided on the first surface or the second surface of the body.

Preferably, the number of the reinforcing portions is two, and is respectively protruded from the first surface and the second surface of the body.
