摘要： Included are: a radar main unit for emitting a radar wave and receiving a reflection wave of the radar wave reflected by an object; and a dielectric substrate in which multiple matching layers each having a protruded shape are regularly arranged on one surface of the dielectric substrate, and the radar wave emitted from the radar main unit enters the multiple matching layers in a state where the other-surface side of the dielectric substrate is attached to a windshield.

摘要： A plurality of primary radiators (1) is classified by combinations of frequency and polarization of radiated radio waves, a plurality of primary radiators (1) belonging to the same class is arranged at positions corresponding to vertexes of one of triangles in a repeated triangle pattern TRPattern, and the shape of a main reflector (2) and the shape and arrangement of the repeated triangle pattern TRPattern are determined such that a direction of a line segment passing through positions corresponding to two vertexes in the triangle is different from a radiation direction of a sidelobe of a radio wave reflected by a main reflector (2) after having been radiated from a primary radiator (1) arranged at a position corresponding to the vertexes.

摘要： A reflector antenna device includes: a primary radiator to radiate a first radio wave in a first frequency band and a second radio wave in a second frequency band lower in frequency than the first frequency band; and a reflector having a reflection face reflecting the first radio wave and the second radio wave radiated by the primary radiator, in which the reflection face of the reflector has a first region including a center point of the reflection face and a second region that is an outer peripheral region of the first region and is provided with a plurality of recesses, and each of the plurality of recesses is configured to allow entrance of the first radio wave, restrict entrance of the second radio wave, and reflect the first radio wave having entered the recess on a bottom face of the recess.

摘要： A first region of a reflection mirror including a center point of the paraboloid of revolution is formed of a conductor. A second region, which is an outer peripheral side of the first region, of the reflection mirror is a region where a plurality of reflection elements, which are conductor patterns, is arranged on a dielectric body overlaid on a base plate conductor. An arrangement pitch of the plurality of reflection elements corresponds to a wavelength of a radio wave in the second frequency band.
