Abstract: A multilayer transmission line includes a multilayer substrate. The multilayer substrate includes a plurality of conductor layers stacked in a predetermined direction with dielectric layers interposed therebetween. The conductor layers in an inner layer part include ground planes, respectively. The inner layer part includes a conductor hole part. The conductor hole part is provided penetrating the respective ground planes in the inner layer part in the predetermined direction. The conductor hole part includes a conductor part to electrically connect the ground planes together. The conductor layer in an outer layer part includes a transmission line and a conversion part. The outer layer part includes the conductor layer as the outermost layer and an inner conductor layer.

Abstract: An antenna apparatus includes a first antenna, a second antenna, and a third antenna. Each of the second antenna and the third antenna transmits a radio-wave signal in a predetermined emitting direction. The first antenna receives a reflection signal resulting from the transmission signal transmitted in the predetermined emitting direction. The second antenna and the third antenna are arranged to be separate from one another in a second direction. The second antenna and the first antenna are arranged to be separate from each other in the first direction, and at least partially overlap each other as viewed in a first direction.

Abstract: An antenna apparatus includes a conductor layer A, a conductor layer B, and a dielectric layer that is sandwiched between the conductor layer A and the conductor layer B. In the conductor layer A, a first antenna, a second antenna, and a connection conductor are formed. The connection conductor is connected to both of the first antenna and the second antenna. In the dielectric layer, a guard conductor is provided. The guard conductor is arranged along an outer periphery of the connection conductor that excludes at least a first connection section and a second connection section of the connection conductor. The first connection section is a connection section of the connection conductor that is connected to the first antenna. The second connection section is a connection section of the connection conductor that is connected to the second antenna.

Abstract: A transmission line assembly is configured such that (i) a first target inner layer is one of second to (N−1)-th pattern layers selected therefrom, and (ii) a second target inner layer is another one of the second to (N−1)-th pattern layers selected therefrom; the second to (N−1)-th pattern layers except for the first and second target inner layers are referred to as inner layers. The transmission line assembly includes band-like first and second slits formed through the ground pattern of a corresponding one of the first and second target inner layers to expose a part of one of dielectric layers; the one of the dielectric layers is adjacent to the corresponding one of the first and second target inner layers. Each of the first and second slits has an edge facing the interlayer line, and the edge of each of the first and second slits is concavely curved toward the interlayer line.

Abstract: Transmission antennas are aligned at a reference distance along a preset direction of alignment. The aperture width of a first reception antenna in the direction of alignment is set to a first width which is less than the reference distance. Second reception antennas each have an aperture width in the direction of alignment set to a second width which is the first width or less and are aligned at a distance which is less than the reference distance along the direction of alignment. The distance between the position of the center of the first reception antenna and the phase center of a second reception antennal located closest to the first reception antenna among the second reception antennas is set to a length that is greater than or equal to the value obtained by multiplying the reference distance by the value obtained by subtracting 1 from the number of transmission antennas.

Abstract: A double-sided board includes a first-type conductor layer, a second-type conductor layer, a waveguide-filled dielectric layer and a waveguide. The waveguide-filled dielectric layer is a dielectric layer provided between the first-type conductor layer and the second-type conductor layer. The waveguide is provided in such a manner as to penetrate the waveguide-filled dielectric layer in a direction from one of the first-type conductor layer and the second-type conductor layer to the other of the two conductor layers. A cross section of the waveguide in a plane parallel to the first-type conductor layer has a longitudinal direction and a lateral direction perpendicular to the longitudinal direction. The cross section of the waveguide has, along the longitudinal direction, a central part and two end parts located respectively on two sides of the central part. A lateral length of each of the end parts is larger than a lateral length of the central part.
