Abstract :
A combined method-of-moment-astigmatic-beam-tracing (MOM-ABT) scheme is proposed for the electromagnetic field analysis of an on-board antenna. The method resorts to a vector spherical wave expansion to link the MOM code to the ABT code. This approach exploits the ability of full wave computation to treat detailed models of the antenna and its nearby structures while ABT is able to perform the analysis of the satellite environment. As an example of the proposed approach, the analysis of the interactions of Galileo satellite TT&C antenna with spacecraft is carried out
