Abstract: A radar apparatus is provided with transmitting means, receiving means, target detection means, azimuth detection means and a cover member. The cover member has a first face and a second face. The first face and second face are not parallel to one another. At least one of the first face and second face is a curved surface which is curved along azimuth detection directions of the azimuth detection means, such as to provide a large phase difference between incoming waves that are received by a plurality of antenna elements and are from within a range of large angular values in the azimuth detection directions of the azimuth detection means.

Abstract: A surface current suppression filter (1) is a bandstop filter that suppresses propagation of a surface current in a predetermined propagation direction on a dielectric substrate (2). The filter (1) is configured such that a plurality of electromagnetic band gap (EBG) rows (10, 20) are arrayed in an array direction. Each EBG row (10, 20) has at least one EBG (11, 21) that is arrayed in a perpendicular direction orthogonal to the array direction. Cutoff characteristics of a first EBG (11) in the first EBG row (10) differs from cutoff characteristics of a second EBG (12) in the second EBG row (20).

Abstract: A radar apparatus that detects an object using radiated waves includes: an antenna surface that includes an element unit that emits a radiated wave for a radar; and a cover member that covers the antenna surface to protect the element unit. The cover member includes an inner refractive surface that is an inner side surface of the cover member on which an undesired wave is incident and is formed into a shape that refracts the undesired wave incident on the inner refractive surface so as to advance towards antenna rear. The antenna rear is a side opposite an antenna front that is a side on which the radiated wave is emitted, with the antenna surface as a boundary. Undesired waves are radiated waves that are emitted outside a range of a predetermined solid angle relative to a normal direction of the antenna surface from a center of the antenna surface from which the radiated waves are emitted.

Abstract: An antenna device includes a dielectric substrate, a ground plate arranged on a first surface of the dielectric substrate, an antenna part arranged on a second surface of the dielectric substrate, and a reflecting part. The reflecting part is arranged around the antenna part and has a plurality of conductor patches each functioning as a reflecting plate. The plurality of conductor patches form a plurality of blocks aligned along a predetermined block arrangement direction. The plurality of blocks are configured such that phases of reflected waves at an operating frequency are different for each of the blocks and phase differences of reflected waves between adjacent blocks are non-uniformly different for each of the adjacent blocks.
