A MICROWAVE ANTENNA CAPABLE OF OPERATING AT HIGH TEMPERATURE, IN PARTICULAR FOR A SPACE-GOING AIRCRAFT

摘要

A microwave antenna capable of operating at high temperature comprises at least one waveguide opening to the outside through an opening in a covering panel and including a tubular portion integrally formed with the panel, projecting inwards therefrom, and connected to the remainder of the panel around the opening, the panel and the integrated waveguide being made of a refractory composite material capable of ensuring microwave propagation and constituting a structural element capable of being raised to high temperature, The waveguide is filled with a refractory dielectric material such as an alumina-alumina type composite material.
