<p>PROBLEM TO BE SOLVED: To provide an antenna device capable of constructing, by means of metal processing alone, a support structure that can reduce a shield region of radio waves.SOLUTION: A support structure 4 is configured so that a plurality of holes 42 for penetrating radio waves reflected by a main reflector 3 or a sub reflector 2 are aligned. Thus, the support structure 4 which can reduce a shield region of radio waves can be constructed by means of metal processing alone.</p> |
