Abstract (en)
[origin: EP0379434A1] The antenna comprises at least one waveguide (20) which opens to the outside through an aperture (12) in a panel (10) of the covering and which includes a tubular portion (22) formed in one piece with the panel, projecting relative to the latter on the inside and connecting with the remainder of the panel around the aperture, the panel with the integrated waveguide being made of a thermostructural refractory composite material, such as carbon/carbon or carbon/ceramic, capable of ensuring propagation of the ultra high frequency waves and constituting an element of a structure which can be taken to high temperature. The waveguide (20) is filled with a refractory dielectric material (26) such as an alumina/alumina type composite material. <IMAGE>
