Abstract: A multilayered substrate includes first, second, and third insulating layers, and a transmission line. The first insulating layer includes first and second surfaces opposite to each other. A signal conductor of the transmission line is on the first surface of the first insulating layer. The second insulating layer is in contact with the first surface of the first insulating layer. The third insulating layer is in contact with the second surface of the first insulating layer. A dielectric loss of the second insulating layer is lower than a dielectric loss of the third insulating layer. A degree of close contact between the first insulating layer and the third insulating layer is higher than a degree of close contact between the first insulating layer and the second insulating layer.

Abstract: An antenna element includes an insulative substrate including first and second main surfaces arranged in an up-down direction. At least one antenna conductor layer is provided on the first main surface of the insulative substrate. At least one insulative substrate non-forming region is provided between the insulative substrate and the antenna conductor layer in the up-down direction. An insulator layer does not exist in the at least one insulative substrate non-forming region. When seen in the up-down direction, all of an outer boundary of at least one antenna conductor overlaps the at least one insulative substrate non-forming region and is not in contact with the insulative substrate. At least one of the at least one insulative substrate non-forming region includes a void.

Abstract: In a transmission line, a thickness of a second section is smaller than that of a first section and of a third section. A center of the second section is above a center of the first section and a center of the third section in a laminated body up-down direction. A distance between a second signal conductor layer and a neutral plane of the second section is shorter than a distance between a first signal conductor layer and a neutral plane of the second section and a distance between a third signal conductor layer and a neutral plane of the second section in the laminated body up-down direction. A length of the second signal conductor layer between first and second interlayer connection conductors is equal to or less than about ½ of a wavelength of a high-frequency signal transmitted by the transmission line.
