摘要： An antenna device includes a ground plane, a flat-plate-shaped first feed element, a flat-plate-shaped second feed element, a first feed line connected to the first feed element, and a second feed line connected to the second feed element. The ground plane, the first feed element, and the second feed element are stacked respective order and spaced apart from each other. At least part of the second feed line is disposed in a same conductor layer as the ground plane and is disposed at a position that overlaps the first feed element as the ground plane is viewed from a plan view.

摘要： A patch antenna is constituted by a radiation element disposed on a substrate and a ground conductor disposed in the substrate. A dielectric member is disposed to at least partially cover the radiation element as viewed from above. The dielectric member is disposed on a side opposite a side on which the ground conductor is disposed as viewed from the radiation element. When a direction of a normal line to the radiation element is assumed as a height direction and when an imaginary plane perpendicular to the height direction is assumed as a reference plane, the dielectric member has a side surface which tilts with respect to the reference plane. The dielectric member has no focal point for a radio wave entering the dielectric member in parallel with the height direction.

摘要： An array accommodated in a housing includes multiple antenna elements. The antenna elements face an inside surface of the housing and are arrayed in a first direction at least one-dimensionally. A waveguide is coupled to the antenna elements of the array antenna and extends from the array antenna toward the inside surface of the housing. The waveguide has a housing-side end face facing the inside surface of the housing and an antenna-side end face facing the array antenna. A length from one end to an opposite end of the housing-side end face in the first direction is greater than a length from one end to an opposite end of the antenna-side end face in the first direction. An antenna device that can improve antenna gain without increasing the size of the antenna module is provided.

摘要： A feed element for feeding power is disposed on a substrate. A first parasitic element is disposed at a position different from a position of the feed element as viewed from above and is electromagnetically coupled with the feed element. A dielectric member is disposed at a position at which the dielectric member at least partially covers the feed element and the first parasitic element as viewed from above. A conductive pattern is disposed on a surface of the dielectric member which faces the feed element at a position at which the conductive pattern matches the first parasitic element as viewed from above. The dielectric member is supported by the substrate as a result of the conductive pattern being electrically connected to the first parasitic element.

摘要： An antenna device includes a casing including an inner surface including connected first and second regions with a corner therebetween. A first antenna opposes the first region with a gap therebetween, and a second antenna opposes the second region with a gap therebetween. A first waveguide extends from the first antenna toward the first region, and a second waveguide extends from the second antenna toward the second region. In a perpendicular projection of an end surface of the first waveguide closest to the first antenna on a plane including the first region, an end surface of the waveguide closest to the inner surface is adjacent to the first corner. In a perpendicular projection of an end surface of the second waveguide closest to the second antenna on a plane including the second region, an end surface of the second waveguide closest to the inner surface is adjacent to the corner.

摘要： A ground plane is disposed on or in an inner layer of a dielectric substrate. Moreover, a feed line is disposed on or in the dielectric substrate. A first antenna element and a second antenna element are supported on the dielectric substrate. The first antenna element and the second antenna element include a first radiating element and a second radiating element connected to the feed line, respectively, and are disposed on a same side when seen from the ground plane. With a height of the ground plane being a reference, a top portion of the second antenna element is located higher than a top portion of the first antenna element. There is provided an antenna device of which the band can be expanded and of which the internal space of the casing can be effectively utilized.
