An RFIC module is provided that includes a base material having a first surface and a second surface opposite to each other; an RFIC mounted on a first surface side of the base material; a first conductor pattern formed on the first surface of the base material; a first insulator film formed on the first surface of the base material and a surface of the first conductor pattern; a second conductor pattern formed on the first insulator film and the first conductor pattern; and a second insulator film covering a surface side of the base material with respect to the first surface. Moreover, the first and second conductor patterns form a circuit connected between RFIC-side electrodes to which the RFIC is connected and antenna-side electrodes facing an antenna conductor pattern.

The invention relates to a UHF RFID transponder with an antenna and an RFID chip, wherein the antenna has a first dipole structure, a first inductive loop and an infeed point, and the first dipole, the inductive loop and the RFID chip are electrically connected to the infeed point. The purpose of the invention is to create an RFID transponder that can be tuned with reduced influence from the geometric tolerances involved in the production of the antenna. As a result, these RFID transponders are intended to be particularly suitable for attaching to glass panes, as the impedance of the antenna can be tuned to the impedance of the RFID chip with less influence from the thickness or material composition of the glass. This task is achieved in that the antenna (2) has a second inductive loop (8) and that this second inductive loop (8) is electrically connected to the infeed point (3) and connected in parallel to the first inductive loop (7).

A process for manufacturing a transaction card includes forming an opening in a card body of the transaction card; inserting an electronic component into the opening; and molding a molding material about the electronic component. A transaction card includes a molded electronic component.

The present invention relates to an encapsulated RFID (Radio Frequency Identification) transponder for the UHF-SHF range, designed to operate in aggressive industrial environments. The encapsulated RFID transponder is composed of an integrated circuit in an SOT 323 package, a near-field antenna made on a printed circuit substrate, electrically connected to the integrated circuit by the use of surface mounting technology, all of which encapsulated in an electrically insulating material, resistant to chemical, mechanical, pressure, and thermal stresses.

RFID devices are provided for use in combination with a food item or other temperature-sensitive item. The RFID devices include an RFID chip and an antenna electrically coupled to the RFID chip, along with a temperature-sensitive member. The temperature-sensitive member is configured to be in a first condition below a selected temperature and a second condition above the selected temperature to signify that the RFID device and associated food item or other temperature-sensitive item have been exposed to a temperature above the selected temperature. The temperature-sensitive member may be incorporated into the antenna to render the antenna at least partially inoperative above the selected temperature. The temperature-sensitive member may instead be configured to exhibit different colors below and above the selected temperature, or a single RFID device may include both types of temperature-sensitive members. Such RFID devices may also incorporate tamper-resistant features and/or accommodate human- and/or machine-readable printed symbols.

A metal cap is provided with an RFID tag that includes a metal cap including a cylindrical main body part, a top plate part formed at one end of the cylindrical main body part, and an opening part formed at the other end of the cylindrical main body part, and an RFID tag disposed on the metal cap. The RFID tag includes an RFIC element disposed in the metal cap, and a loop antenna connected to the RFIC element. At least a portion of a loop opening of the loop antenna extends in a circumferential direction R of the metal cap while being exposed from an opening edge of the opening part of the metal cap to the outside of the metal cap.
