Efficient techniques based on the CBFM for the analysis of on-board antennas

A technique for antenna placement on electrically large structures is presented in this paper. The method of moments matrix is compressed with the characteristic basis function method so that it can be fitted into the available RAM memory. Potential positions of the antenna are handled as duplicated blocks with one version containing the antenna and the other one not. After that, a partial solution of the structure is accomplished so that it can be resumed from a common point in order to save time.
