摘要:
An RFID tag has an antenna element including an antenna substrate equipped with an IC chip and a conductor pattern, an artificial medium, and a first insulation layer sandwiched between the antenna element and the artificial medium. The artificial medium has a single first conductive element placed on an upper surface of a dielectric layer and a single second conductive element placed on a lower surface of the dielectric layer.

摘要:
A method of making by extrusion-molding an elongated window frame used for a window panel of a vehicle is to use an extrusion molding die which includes a slide core defining the cross-sectional shape of the window frame, and to move the slide core in the extrusion-molding die so that the cross-sectional shape of the window frame is continuously changed along the direction of the length.
