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 hightemperature comprises at least one waveguide opening to theoutside through an opening in a covering panel and including atubular portion integrally formed with the panel, projectinginwards therefrom, and connected to the remainder of the panelaround the opening, the panel and the integrated waveguidebeing made of a refractory composite material capable ofensuring microwave propagation and constituting a structuralelement capable of being raised to high temperature, Thewaveguide is filled with a refractory dielectric material suchas an alumina-alumina type composite material.
