Abstract :
The paper presents data on radiotechnical characteristics of antennae and reflectors for mm and sub-mm wavelength ranges, made of carbon-graphite materials (CGM). It is shown that the reflectivity value of plane reflectors made of different kinds of CGM depends mostly on the surface roughness being close to that of metallic reflectors, and does not change significantly under neutron irradiation. Characteristics of CGM-made antennae are not much different from those for antennae made of metal. Pyramidal antennae made of CGM maintains its properties under imitated plasma disruption much better than a similar metallic one would.
