Abstract :
The authors describe the function of the ETS-VI (Engineering Test Satellite-VI) spacecraft and give a brief description of the onboard antennas and the problems associated with antenna integration. The configuration of the fixed and mobile communication antenna system is shown. The deployed configuration of the structural model antenna consists of tower, main and subreflectors for 20/S and 30/C, Ka-band cluster horns for 20 and 30 GHz, frequency selective surfaces for 20/S and 30/C, a C-band horn, an S-band horn, and an antenna pointing mechanism for each subreflector. The accurate integration of the antenna components to the fixed points of the tower is discussed.<>
