A phased array antenna is formed from an array of apertures having walls containing phase shifter devices for phase shifting and beam steering a radiated beam of the phased array antenna. The phase shifter devices are interconnected with an interconnect structure formed from substrate slats that form the walls of the apertures. The substrate slats may be thin film circuitized column slats having a metal substrate, dielectric layers, metal bias/control circuitry, a shielding layer, and circuit terminations to connect to a phase shifter device attached to the substrate slat.

A phased array antenna with an egg crate array structure is formed from metallic row slats that form a floor and ceiling of each array element. Column slats with slots engage the row slots to form the egg crate array structure. EMXT devices are located on the column slats such that a pair of EMXT devices form array element walls. The column slats are formed from U-shaped column strips configured such that a left side of the U-shape forms a left-hand side of each array element in a column and a right side of the U forms an opposing right-hand side. The column strips sides are mounted back-to-back with sides of adjacent column strips to form the column slats. Circuit devices for operation of the antenna are mounted on the U-shaped column strip and a connector is mounted at an apex of the U-shaped column slat.
