Abstract
A first antenna, a second antenna, and a waveguide structure are housed in a single cabinet. An operating frequency of the second antenna is higher than an operating frequency of the first antenna. The second antenna is an array antenna including a plurality of radiating elements. The waveguide structure is present outside a range of a half-value angle of a main beam as viewed from the first antenna, includes a unit waveguide disposed in a route of a radio wave received by the second antenna, and further attenuates a radio wave with the operating frequency of the first antenna.
