摘要： A planar antenna includes a dielectric layer including a first surface and a second surface on a side opposite from the first surface, an antenna conductor provided on the first surface, a ground conductor provided on the first surface or the second surface, or provided on both of the first surface and the second surface, and a transmission line including a signal line that is connected to the antenna conductor or provided in proximity to the antenna conductor, wherein a dielectric portion of the dielectric layer that is in contact with the signal line has a loss tangent of 0.007 or less at 28 GHz.

摘要： The present invention relates to a laminated glass for vehicle, including a first glass plate and a second glass plate joined to each other by an intermediate film, in which the first glass plate has a second main surface facing the intermediate film; the laminated glass has a first region with the second glass plate and a second region with no second glass plate in a plan view; the laminated glass has a filling portion that includes an electromagnetic wave transmission member and is disposed continuously from the second main surface on the second region toward a space between the first glass plate and the second glass plate in the first region to cross the entire boundary between the first region and the second region; and the second region is higher in transmittance of millimeter waves than the first region.
