The results of reflectivity study of metalized carbon-fiber panels for antennas of satellite radiometers in the MM and SubMM ranges are presented. The panels reflection losses with metalized polyimide film strips pasted on them and the effect of overlap between the film strips on the reflection losses were investigated. A numerical calculation based on consideration of the problem of plane wave scattering at the real overlap structure showed that for the electric field polarization along and across the overlap, the reflection loss at frequency 200 GHz differs by ~ 13 %.
