Abstract: An RFID tag that includes an RFID tag body having a conductor in a loop-like shape or a coil-like shape, and metal fixtures for fixing the RFID tag body to a metal surface of an article. The conductor is formed in an element body in a rectangular parallelepiped shape that has first and second side surfaces facing each other, third and fourth side surfaces facing each other and orthogonal to the first side surface, a top surface, and a bottom surface serving as a mounting surface. A plane of an opening of the conductor is parallel to the first side surface and the second side surface, and the metal fixtures each include a first portion protruding along an extension surface of the bottom surface, a second portion disposed along the third side surface or the fourth side surface, and a third portion disposed along the top surface.

Abstract: A wireless IC device includes a substantially rectangular parallelepiped dielectric body, a metal pattern that is provided on the surface of the dielectric body via a film and functions as a radiator, and a wireless IC element coupled to feeding portions of the metal pattern. The dielectric body has a laminated structure including a folded flexible dielectric layer. Surfaces of the dielectric layer which face each other after the dielectric layer has been folded are non-bonded surfaces.

Abstract: A dielectric lens which is produced by injection molding of an expandable material consisting of a synthetic resin, a foaming agent and a dielectric constant conditioner. The expandable material is injected into a cavity of a foaming mold up to at least about 80 percent by weight and at least about 100 percent by volume of the capacity of the cavity and is foamed at an expansion ratio of not more than about 1.3. During the foam molding, the surface of the foam-molded body is solidified to be a radome layer. Then, the foam-molded body is transferred from the foaming mold to a shaping mold, in which the foam-molded is cooled down naturally. Further, a fitting tab is provided integrally with the foam-molded body at the edge of the radome layer.

Abstract: A dielectric lens is formed by laminating a plurality of dielectric sheets having different diameters along a focal axis of the lens. The first dielectric sheet is formed by injecting a dielectric material in a molten state at a predetermined pressure and cooling and solidifying the dielectric material. Each successive dielectric sheet is formed by injecting the dielectric material in a molten state on the preceding dielectric sheet and cooling and solidifying the dielectric material, so that each successive dielectric sheet and each immediately preceding dielectric sheet are fusion-bonded to each other.

Abstract: The present invention is for providing a production method of a dielectric lens with the excellent productivity, capable of achieving the shape accuracy or density homogeneity of the demanded level, and capable of injection molding of a matching layer without forming a gap with respect to a lens main body. A lens main body is formed by the injection compression molding method, using a composite dielectric material containing a thermoplastic resin as the dielectric material for the lens main body. After forming a matching layer (first surface side matching layer) on either surface of the front or rear surfaces (first surface) side of the lens main body, and injecting a matching layer material, a matching layer (second surface side matching layer) is formed on the other surface of the lens main body (that is, the matching layer is formed by the two operation injection molding method of injecting to one surface side of the lens main body, and then injection to the other surface side).
