  • Patent number: 11336009
    Abstract: 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.

  • Patent number: 9337546
    Abstract: A part of bent end sections of a slot is configured to overlap with a waveguide inner wall when seen from the normal direction of a narrow wall surface of a waveguide at which the slot is provided. Thus, the conductance of a single slot can be reduced by adjusting the joined amount of a tip section of the slot and the inner wall of the waveguide. As a result, even in the case where the number of slots provided per waveguide is increased while a waveguide width is restricted to be short with respect to a slot length, impedance matching with a waveguide bonding section can be taken.
