Abstract: An millimeter wave antenna includes an antenna body adapted to transmit and receive an electromagnetic wave of a millimeter wave band; and a radome that covers a transmitting and receiving surface of the antenna body. The transmitting and receiving surface and the radorm are apart from each other and have a space therebetween. The radome includes a gap adapted to allow the electromagnetic wave of the millimeter wave band to pass through the gap. A radar apparatus for vehicle includes the millimeter wave antenna.

Abstract: An antenna device comprises a first dielectric substrate; first and second antenna elements arranged on a first surface of the first dielectric substrate; a ground conductor arranged on a second surface of the first dielectric substrate; and an EBG structure arranged between the first and second antenna elements. The EBG structure comprises first patch conductors that are each arranged in contact with the first surface of the first dielectric substrate and are each electromagnetically coupled with the ground conductor; second patch conductors that are each arranged in a prescribed distance from the first surface of the first dielectric substrate in a direction opposite to the second surface, and are each electromagnetically coupled with corresponding one of the first patch conductors; and first connection conductors that electrically connect the first patch conductors with the second patch conductors.
