Abstract: To suppress downward radiation of electromagnetic waves from an antenna unit.
An antenna unit to be used by being installed so as to face a window glass for a building, the antenna unit comprising a plurality of array antennas, wherein each of the plurality of array antennas has a plurality of radiating elements and at least one conductor situated on an interior side relative to the plurality of radiating elements, and where the effective wavelength of the plurality of array antennas at the operation frequency is λ, and an integer of 0 or more is n, the distance from the center of the upper radiating element among the plurality of radiating elements to the upper edge of the conductor in the up-and-down direction is (0.5+n)λ±0.22λ, as seen in a plan view of the antenna unit.
