Abstract: A container including an RFID module is provided that includes a base, a metal film, and a slit. The base has an insulating property. The metal film is on a first main surface of the base. The slit separates the metal film into a first metal region and a second metal region. The RFID module includes an RFIC element, a filter circuit configured to transmit a current due to an electromagnetic wave at a natural resonance frequency being a communication frequency to the RFIC element, and first and second electrodes to be connected to the filter circuit. The first electrode of the RFID module and the first metal region of the metal film are electrically connected to each other. The second electrode of the RFID module and the second metal region of the metal film are electrically connected to each other.

Abstract: An RFID tag is provided that has reduced size while a decrease in communication distance is prevented. The RFID tag includes an inductor element having a coiled antenna built in a substrate and an RFIC element mounted on a mounting surface of the substrate and electrically connected to the coiled antenna. The coiled antenna is disposed such that a winding axis becomes parallel to or inclined with respect to the mounting surface of the substrate. The area of the RFIC element viewed in a direction orthogonal to the mounting surface of the substrate is larger than opening area of the coiled antenna viewed in winding axis direction of the coiled antenna. The RFIC element is disposed without overlapping at least a portion of opening region of the coiled antenna when viewed in winding axis direction of the coiled antenna.

Abstract: In an impedance matching circuit, first to fourth inductors are formed by a conductor pattern of a coil shape, and a fifth inductor is formed by a conductor pattern of an unwound shape. The first inductor and the third inductor are respectively formed in different layers of a substrate and are arranged in such a relationship as to have coil openings overlapping each other. Moreover, the second inductor and the fourth inductor are respectively formed in different layers of the substrate and are arranged in such a relationship as to have coil openings overlapping each other. Two coils interposing the mounting position of the RFIC are in a 180° rotational symmetry relationship.
