Abstract: “Satellite communication in motion (SCM) ”enjoys the advantages of wide coverage area,no topography or region restriction,stable and reliable transmission,and mobile communication,exhibiting wide and promising prospects in both military and civilian fields． Antenna mask is used to protect " SCM" antenna of the necessary equipment． This paper introduces the design,manufacture process,and applications of high performance antenna mask of SCM． Through analyzing the basic properties for high performance antenna mask materials,a lay up design for Ku-band antenna mask is made． Structure optimization is conducted by using the ANSYS software． Also,process and electrical property optimization designs are made for suitable use． Finally,the application prospects of the antenna mask manufactured according to above design are discussed．

Key words: Ku-band, satellite communication in motion, radome, material property
