PROBLEM TO BE SOLVED: To provide an antenna device that provides each sub-array antenna formed by gathering a plurality of elementary antennas with a phase shifter and forms a beam by bundling the phase shifters, capable of suppressing a grating lobe and suppressing gain reduction of a main beam.SOLUTION: In the antenna device that provides each sub-array antenna formed by gathering a plurality of elementary antennas with a phase shifter and bundles them to form a beam, the plurality of elementary antennas are periodically arranged, and the sub-array antenna is formed of the elementary antennas included by a tile filling in a plane an opening plane of the antenna non-periodically. |
