摘要： An array antenna device includes a classifying unit that classifies rotating devices into a plurality of groups with different priorities under the condition that the number of rotating devices included in one group is equal to or less than the number of rotating devices that is calculated by a number-of-drivable-devices calculating unit; and a rotation instructing unit that selects groups in descending order of priority from among the plurality of groups and drives, each time one group is selected, all rotating devices included in the group, and the classifying unit performs the classification in such a manner that, among the rotating devices, a rotating device that rotates an element antenna with a higher importance level is classified into a group with a higher priority.

摘要： A dielectric substrate is provided between a first waveguide member and a second waveguide member. The second waveguide member includes a plurality of slots for radiating a horizontally polarized wave. The dielectric substrate is provided with a plurality of line-shaped conductors arranged obliquely with respect to the waveguide axial direction and waveguide wall conductors as waveguide wall surfaces, and includes conductor-removed portions that function as vertically-polarized-wave radiation slot parallel to the waveguide axial direction. The waveguide wall conductors are connected by vias.

摘要： In a conventional antenna device, transmission radio waves transmitted from a transmitting antenna traveling directly to a receiving antenna are blocked by a shield wall disposed between the receiving antenna and the transmitting antenna. However, some of the transmission radio waves are diffracted at the edge of the shield wall and enter the receiving antenna as diffracted waves, affecting the reception of the reception radio waves. In view of this, the shield wall and a polarized wave converter unit are disposed between the transmitting antenna unit and the receiving antenna unit. As a result, vertically polarized wave components of the diffracted waves are converted by the polarized wave converter unit to circularly polarized wave components that are less affecting the reception of the reception radio waves in the receiving antenna, and the diffracted waves are prevented from affecting the receiving operation of the receiving antenna.
