Problems solved by technology

[0008] However, since such a general-purpose insert is only coated with a thin film on the IC chip and the antenna, it can cause failure, malfunction, damage, etc. due to external shocks, etc.
For example, pallets, containers, etc. for goods are always in a state of being subjected to physical and mechanical external force / shock. In the case of an RF tag used for mounting on such an object, it is possible to keep the embedded part unchanged. prone to failure / damage, etc.

Abstract

The present invention provides an RF tag which improves the communication characteristics of an inlay by using an auxiliary antenna, while protecting the inlay from physical and mechanical external forces, shocks, or the like without being subjected to the constraints of a dipole antenna. The RF tag has the inlay 10 comprising an IC chip 11 and only a loop circuit antenna 12 on which the IC chip 11 is mounted and not comprising another antenna; a casing 50 for accommodating the inlay 10 therein; and a planar top cover 20 covering one surface side of the casing 50. The top cover 20 is formed ofa prescribed metallic material and comprises a notch 21 opening at least at one side. The inlay 10 is disposed within the casing 50 so as to be positioned inside the notch 21. The top cover 20 functions as an antenna of the inlay 10 by being electrically connected to the inlay 10.

Description

technical field [0001] The present invention relates to an RF tag used to be attached to any article or object such as a pallet for cargo, a container, etc., and particularly relates to an RF tag that accommodates an IC chip and an antenna in a case or the like. RF tags for protection. Background technique [0002] Generally, a so-called RF tag is widely used for an arbitrary article or object, and has a built-in IC chip that stores predetermined information on the article or object in a readable and writable manner. [0003] RF tags are also called RFID (Radio Frequency Identification) tags, IC tags, non-contact tags, etc., and are so-called tags obtained by sealing / coating an electronic circuit equipped with an IC chip and a wireless antenna with a base material such as a resin film. An ultra-small communication terminal with an insert (insert) formed in the shape of a label (tag), which can read or write given information wirelessly through a read / write device (reader / wr...
