Abstract: Antenna subassemblies suitable for use in phased array antennas are disclosed, as are phased array antenna assemblies and aircraft comprising phased array antenna assemblies. In one embodiment, an antenna subarray assembly comprises a thermally conductive foam substrate, a plurality of radiating elements bonded to the foam substrate, and a radome disposed adjacent the radiating elements. The subarray assembly presents a triangular shape when viewed in plan view, and the plurality of radiating elements are arranged in a triangular array on the foam substrate. In some embodiments, a plurality of subarray assemblies may be assembled to form an antenna assembly. In further embodiments an aircraft may be fitted with one or more antenna assemblies. Other embodiments may be described.

Abstract: A phased array antenna tile which is steered by microelectromechanical system (MEMS) switched time delay units (TDUs) in an array architecture which reduces the number of amplifiers and circulators needed for implementing an active aperture electronically scanned array antenna so as to minimize DC power consumption, cost and mass of the system, making it particularly adaptable for airborne and spaceborne radar applications.
