AB It is imperative to test the mechanical, electrical and thermal-optical properties of MM and sub-MM reflector antennas. Electrical, thermal and optical properties are very important and high-accurate measurements lead, obviously, to more accurate results in applications. This paper deals with measurement of electrical reflectivity in the range 110-200 GHz. Reflectivity has been measured for a number of samples, which represent materials used in reflector antennas. Both metal samples and carbon-fibre samples were tested in a dedicated facility available for this purpose at the Applied Physics Institute in Nizhny Novgorod (IAP). The test facility is shortly discussed, with techniques for data extraction. Calibration is done with high quality silver coated mirrors and aluminium control samples. Accurate results have been derived with indicative interesting results.
