Electromagnetic properties of metal space frame radomes for use in satellite communication earth stations

The authors examine the electromagnetic properties of metal space frame (MSF) radomes and evaluate the RF performance of these radomes for satellite communication earth station application. It is demonstrated that the CCIR (International Radio Consultative Committee) sidelobe envelope specification can be satisfactorily met by Electronic Space Systems Corporation´s MSF radome covered earth station with conventional antennas. A typical co-pol scattering topographical map is simulated for the M9000 MSF radomes. The resulting antenna pattern for the M9000-MSF-radome-enclosed earth station is illustrated, showing that the number of penetrations of the CCIR envelope is much below the 10% allowance according to the CCIR recommendation.<>
