    摘要: An antenna device that can simplify configuration for controlling directional characteristics, and an array antenna device that can avoid complexity for control even if the number of unit antennas disposed increases are provided. The device includes: an element part 100 having an excitation element 1, a first passive element 11 having first and second conductive parts 11a and 11b, a second passive element 21 having third and fourth conductive parts 21a and 21b, a first switch 12 controlling conduction between the first and second conductive parts, and a second switch 22 controlling conduction between the third and fourth conductive parts; and a controller 200 outputting an electric signal for controlling conduction of the first and second switches. The controller outputs identical DC signal to the first and second switches, and one of the first and second switches is brought into conduction while the other one is brought out of conduction.

    摘要: Provided is a waveguide slot array antenna apparatus having a polarized wave plane in a direction oblique to a tube shaft of a waveguide, in which an excitation distribution of opening portions for radiating or receiving electromagnetic waves is appropriately attained. The waveguide slot array antenna apparatus includes a waveguide slot array antenna formed of a rectangular antenna waveguide which has a rectangular section orthogonal to a tube axis, in which: the rectangular antenna waveguide has one end side thereof in a tube axial direction serving as a feeding port and another end side short-circuited; the antenna waveguide has a plurality of slender rectangular opening portions for radiating or receiving an electromagnetic wave arranged at intervals of about »g/2 (»g is an intra-tube wavelength) along the tube axis on a first wide plane of a pair of wide planes that are parallel to the tube axis; the plurality of slender rectangular opening portions each have the same predetermined angle with respect to a center line parallel to the tube axis of the first wide plane; the opening portions adjacent to one another are alternately arranged at opposite positions with respect to the center line; the opening portions located on one side with respect to the center line of the first wide plane each have a length longer than about »f/2 (»f is a free space wavelength), and the opening portions located on another side each have a length shorter than about »f/2.
