A system and method uses an active manifold for an antenna array. The manifold can be assembled by a method including providing a first set of cards including a first set of antenna elements and a corresponding number of integrated circuit based time delay units or phase shifters for the first set of antenna elements. The first set of antenna elements is associated with a row of the antenna array. The method also includes providing a second set of cards including a second set of antenna elements and a corresponding number of integrated circuit based time delay units or phase shifters for the second set of antenna elements. The second set of antenna elements is associated with a column of the antenna array.
