Provided is a conductive film for antennas, in which a conducting film and a substrate made of a polycarbonate resin material containing a polycarbonate resin are laminated, and the polycarbonate resin contains, as main constituent units, a unit (A) represented by the following formula (1) and/or a unit (B) represented by the following formula (2). The conductive film for antennas has low dielectric characteristics and bendability, can form an antenna with a low transmission loss, and has excellent adhesion to the conducting film. (In the formula (1), Rand Reach independently represent an alkyl group having 1 to 6 carbon atoms or a halogen atom, and Rand Reach independently represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or a halogen atom.) (In the formula (2), Rand Reach independently represent an alkyl group having 1 to 6 carbon atoms or a halogen atom, Rand Reach independently represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or a halogen atom, Rrepresents a halogen atom, an alkyl group having 1 to 20 carbon atoms, or a cycloalkyl group having 3 to 20 carbon atoms, and n represents an integer of 0 to 10.)

Conductive film for antennas, and antenna

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 elementsthroughthrough, andthroughare arranged in the same plane, and the rhombic antenna sections are connected by linear linking elementsthrough. Linear detour elementsandare connected to the pair of vertices of the rhombic antenna sections arranged at each end. Feed pointsandare 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.

Antenna apparatus

A device displays images such that a driver can easily recognize an obstacle. The device includes a measurement for measuring a distance and direction to an obstacle, a comparison section for comparing the measured distance with a threshold value, a viewpoint determination section for determining a first viewpoint when the measured distance is larger than the threshold value and a second viewpoint based on the measured direction when the measured distance is not larger than the threshold value, an image generating section for generating an image representing an environment as seen from the first viewpoint when the first viewpoint is set and an image of a particular spot representing a view of the vehicle and the obstacle as seen from an area of the second viewpoint when the second viewpoint is set, and a display section for displaying the bird's eye image or the image of the particular spot.
