Antenna subassemblies (100) suitable for use in panels of a phased array antenna assembly are disclosed e.g. for use in vehicles like aircrafts and satellites. An antenna subarray assembly (100) comprises a thermally conductive foam substrate (140), a plurality of radiating elements (150) bonded to the foam substrate, and a radome (170) disposed adjacent the radiating elements (150). The subarray assembly (100) presents a triangular shape when viewed in plan view, and the plurality of radiating elements (150) are arranged in a triangular array on the foam substrate (140). The thermally conductive foam enables passive cooling. Embodiments also describe MMIC amplifiers and thermal control by a phase change material. |
