    摘要： A superconducting microstrip filter of relatively small size exhibits desired power performance while having a sharp cutoff characteristic. This filter comprises a resonator section (22) including at least one resonator (23), and the resonator (23) has line patterns (25) that partially form part (31) for reducing current density. The filter also comprises an input line (21) adjacent to the resonator (23) in the front stage, and the input line (21) includes parts (41, 41') for reducing current density. The input line (21) can be composed of normal conductor.

    摘要： An object of the present invention is to provide a tag patch antenna in which the communication distance is not deteriorated despite being attached to an object including a liquid or a metal and which has a simple and inexpensive structure, and an RFID tag using the tag patch antenna. The tag patch antenna 3 is configured by including a slit 5 formed in the vicinity of an edge of an antenna pattern along part 6 (6a, 6b) of the edge, and a feeding point to which a tag LSI is connected and which is formed by cutting the middle portion of the part 6 of the edge separated by the slit 5 from the body of the antenna pattern 3 by the width of the slit 5. The tag patch antenna 3 and the tag LSI 4 connected to the feeding point are molded a resinous body 2b such as PET or the like in the shape of a card. The resinous body 2b is adhered to a marketed universal resinous substrate 7 as a dielectric with an adhesive 9. Onto the surface opposite to the adhesive surface with the universal resinous substrate 7, a conductor film 8 is pasted.
