Abstract
An array antenna includes an antenna substrate including a first ceramic member, an insertion member and a second ceramic member sequentially stacked, antenna pattern portions arranged on the antenna substrate in an array form, and shielding vias disposed inside the antenna substrate and extending in a thickness direction of the antenna substrate. The shielding vias are disposed in thickness areas of the antenna substrate corresponding to the antenna pattern portions.
