Abstract
An antenna device includes: a substrate at which a transmission antenna and a reception antenna are provided; and a radome provided facing the substrate, the radome includes: a transmission side radome facing the transmission antenna; and a reception side radome facing the reception antenna, and a region in which a gain is increased as compared with a case in which the radome is not provided in a beam pattern in a plane of the transmission antenna including a predetermined direction and a region in which a gain is increased as compared with a case in which the radome is not provided in a beam pattern in the plane of the reception antenna are at different angular positions.
Claims19
An antenna device comprising:
- a substrate at which a transmission antenna and a reception antenna are provided;
- and
- a radome provided facing the substrate,
- wherein the radome comprises:
- a transmission side radome facing the transmission antenna;
- and
- a reception side radome facing the reception antenna, and
- wherein a region in which a gain is increased as compared with a case in which the radome is not provided in a beam pattern in a plane of the transmission antenna including a predetermined direction and a region in which a gain is increased as compared with a case in which the radome is not provided in a beam pattern in the plane of the reception antenna are at different angular positions, and
- wherein the beam pattern of the transmission antenna has, at an angular position on one side with respect to a main lobe, a first change region in which a gain is increased as compared with the case in which the radome is not provided, and
- wherein the beam pattern of the reception antenna has, at an angular position on other side with respect to the main lobe, a second change region in which a gain is increased as compared with the case in which the radome is not provided.
