摘要： An antenna apparatus capable of main beam direction switching is provided that achieves high gain with a small, planar configuration. Rhombic antenna sections composed of linear elements 101a through 101d, 102a through 102d, and 103a through 103d are arranged in the same plane, and the rhombic antenna sections are connected by linear linking elements 104a through 104d. Linear detour elements 105a and 105b are connected to the pair of vertices of the rhombic antenna sections arranged at each end. Feed points 106a and 106b are provided at the other opposite two pairs of vertices of any of the rhombic antenna sections, and the opposite vertices of the other rhombic antenna sections are connected by linear elements. A plate reflector is arranged at a distance h from, and parallel to, the surface on which the rhombic antenna elements are arranged.

摘要： A radar apparatus includes: antenna elements, a transmitter, a receiver, a first antenna switch which selectively connects first power feeding points of each of the plurality of the antenna elements and the transmitter, a second antenna switch which selectively connects second power feeding points of each of the plurality of antenna elements and the receiver, and a control portion which controls a connection of the first and second antenna switch. Two or more of the antenna elements have different directivity.

摘要： An object of the present invention is to provide a vehicle surrounding display device capable of displaying images such that a driver can visually recognize an obstacle more easily. The vehicle surrounding display device 1 comprises a measurement section 11 for measuring a distance and direction from a vehicle A to an obstacle B in the vicinity of the vehicle; a comparison section 12 for comparing the measured distance with a predetermined threshold value; a viewpoint determination section 13 for determining a predetermined first viewpoint when a comparison result indicates that the measured distance is larger than the threshold value, and for determining a second viewpoint based on the measured direction when the comparison result indicates that the measured distance is not larger than the threshold value; a image generating section 14 for generating a bird's eye image representing an environment in the vicinity of the vehicle as seen from the received first viewpoint when the first viewpoint is set, and generating an image of a particular spot representing a view of the vehicle A and the obstacle B as seen from an area in the vicinity of the received second viewpoint when the second viewpoint is set; and a display section 15 for displaying the bird's eye image or the image of the particular spot.
