A balanced electrode having two balanced transmission electrodes vertical to the extending direction of the feeder electrode and extending in parallel. The two balanced transmission electrodes are connected to the feeder electrode and separated by an interval of ½ of a wavelength of a transmission/reception signal. A radiation electrode having a first electrode connected to the one of the two balanced transmission electrodes and a second electrode connected to the other of the two balanced transmission electrodes and is positioned parallel to the feeder electrode.

    • A conductor member contains a linear feed waveguide extending in a fixed direction and a plurality of horn antennas coupled to the feed waveguide and set at an interval of about one half of a wavelength in the extending direction of the feed waveguide. The horn antennas are formed by horns and coupling waveguides, and the coupling waveguides are set so as to partially enter the feed waveguide. When the size of the spatial coupling portion formed by the entrance is changed, the degree of coupling between the feed waveguide and each of the coupling waveguides changes.

    • A design process first determines a desired aperture distribution, then converts the electric power conservation law, Snell's law on the rear face side of a dielectric lens, and the formula representing light-path-length constraint, into simultaneous equations, and computes the shapes of the surface and rear face of the dielectric lens depending on the azimuthal angle θ of a primary ray from the focal point of the dielectric lens to the rear face of the dielectric lens, and then reduces the light path length in the formula showing light-path-length constraint by an integral multiple of the wavelength when the coordinates on the surface of the dielectric lens reach a predetermined restriction thickness position. A dielectric lens is designed by sequentially changing the lazimuthal angle θ from its initial value, and also repeating the second and third steps. Thus, downsizing and quantification is realized by zoning while keeping antenna properties at the time of constituting a dielectric lens antenna in a good condition.

    • An antenna apparatus includes two circular waveguides including a fixed-side circular waveguide and a rotation-side circular waveguide, each having a propagation mode in a TM01 mode, and being arranged coaxially with each other while a waveguide-side choke is provided between the two waveguides. A rectangular waveguide is connected to the fixed-side circular waveguide. Thereby, the high-frequency signal fed from the rectangular waveguide to the fixed-side circular waveguide can be radiated from a primary radiator to which the rotation-side circular waveguide is connected. While the circular waveguides and the waveguide-side choke can constitute a rotary joint, by rotating the primary radiator together with the rotation-side circular waveguide, scanning can be carried out with a high-frequency signal radiated from the primary radiator.
