Antenna and vehicle

A vehicle comprising:

• an antenna;
• and
• a supporting member configured to support the antenna,
• wherein
• the antenna includes:
• a first conductor having a surface having a first shape in plan view;
• a feed element disposed over the surface of the first conductor;
• a second conductor disposed over the surface of the first conductor at a distance from the feed element, the distance being greater than a distance between the feed element and the surface, the second conductor having a second shape that is a sheet-like shape in plan view, the second conductor being disposed to overlap the surface of the first conductor when viewed from a direction perpendicular to the surface of the first conductor;
• and
• a third conductor electrically connected to the second conductor at least in terms of high frequency, at least a part of the third conductor being located closer to the first conductor than the second conductor is located, in the direction perpendicular to the surface of the first conductor,
• the first shape is larger in area than the second shape,
• the at least the part of the third conductor is located farther than a part of the second conductor with respect to the feed element in a direction along the surface of the first conductor,
• the third conductor is not electrically connected to the first conductor in terms of direct current,
• a first distance exists between the feed element and the first conductor, a second distance exists between the at least the part of the third conductor and the first conductor,
• the second distance is less than twice the first distance,
• the feed element and the second conductor are disposed along a predetermined direction parallel to the surface of the first conductor, and
• the supporting member supports the antenna, with the predetermined direction corresponding to a traveling direction of the vehicle.
