Electronically-scanned antenna, has active modules arranged in parallel relative to predetermined grid and between flat beams whose walls are flexible for being deformed under action of pressure of pressurized coolant traversing beams

摘要

The antenna has active modules (11), each with a transmission-reception circuit (20). The modules are arranged in parallel in correspondence with a predetermined grid (15) of a transmission surface. The modules are arranged between parallel, hollow flat beams (12) traversed by a pressurized coolant. Walls of the beams are flexible for being deformed under the action of pressure of the coolant.
