PROBLEM TO BE SOLVED: To obtain a dual grid antenna which does not use an intercostal, and can exclude blocking and loss by the intercostal. SOLUTION: The antenna is provided with a first driving unit which supports a front face reflection mirror turnable freely, detects an angle of the reflection mirror, and simultaneously performs angle adjustment of the mirror axis direction; a second driving unit which supports a rear face reflection mirror turnable freely, detects an angle of the front face reflection mirror, and simultaneously perform angle adjustment of the mirror axis direction; and a control unit which controls the first and the second driving unit. It controls angles of the front face reflection mirror and the rear face reflection mirror so that the mirror axis of the front face reflection mirror and the mirror axis of the rear face reflection mirror agree.
