Abstract: An antenna device comprising: one or more substrates; a first radiating element disposed on a first region of a surface of the one or more substrates that face a cover covering the antenna device; a second radiating element disposed on a second region of the surface of the one or more substrates that face the cover; a first reflecting plate that reflects an electromagnetic wave from the first radiating element; and a second reflecting plate that reflects an electromagnetic wave from the second radiating element, wherein the first reflecting plate and the second reflecting plate take different positions in a direction perpendicular to the surface of the one or more substrates that face the cover, and the first region and the second region are regions that do not overlap each other on the surface of the one or more substrates that face the cover.

Abstract: A radar apparatus includes an antenna composed of an end-fire array antenna and including a plurality of antenna elements; and a circuit board in which the plurality of antenna elements is disposed side by side in a first direction. At least one of the plurality of antenna elements is parallel to a substrate surface of the circuit board. A directivity of at least one of the plurality of antenna elements is set to a third direction tilted with respect to the first direction and a second direction orthogonal to the first direction.

Abstract: A circuit board includes: a substrate; a first power feed line disposed so as to be close to a plurality of radiating elements provided on a surface of the substrate and to extend in a first direction; a first connection conductor extending in a second direction orthogonal to the first direction, one end of the first connection conductor being connected to the first power feed line substantially at its central portion in the first direction; and a second power feed line that has a first line part extending in a third direction orthogonal to the second direction, the first line part joining to another end of the first connection conductor, and also has a second line part branching from the first line part, the second line part joining to the other end from a third direction side.
