Microwave antenna capable of operating at high temperature, in particular for a space-going aircraft
First Claim
1. A microwave antenna for operation at high temperatures on a surface of an atmospheric vehicle, comprising:
- a refractory composite material panel forming part of the surface of said vehicle and connected to said vehicle as a structural member thereof;
at least one waveguide integrally formed in said panel from said refractory composite material, each waveguide comprising a tubular portion integrally formed with said panel and projecting inward from said panel so as to provide an opening in said panel through said tubular portion;
an antenna body within said vehicle and connected to said tubular portion across said opening; and
said panel and said tubular portion being formed in one piece and made of refractory composite material capable of ensuring microwave propagation and maintaining structural integrity when heated to high temperatures characteristic of atmospheric friction on hypersonic missiles and space vehicles.

Abstract
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.
