Radio wave transmitting device, antenna and spacecraft

摘要

A device for transmitting radio waves comprises an item of transmitting equipment for a telecommunications antenna, a membrane for thermally protecting the reflector, and means for attaching the thermal protection membrane to the item of equipment. The thermal protection membrane is furnished with a plurality of elastic tensioners designed to keep the thermal protection membrane stretched between a first active face of the item of transmitting equipment and space, irrespective of the thermal expansions of the membrane. The item of transmitting equipment occurs in a predetermined temperature range when the attachment means attach the membrane to the item of transmitting equipment.
