Abstract

We describe here a real case application of a formerly presented compression technique for the method of moments. This method is based on a QR compression of the impedance matrix off-diagonals blocks. In this letter, it is extended to the multilevel three-dimensional case, and applied to the radiation of an antenna mounted on a car model. The ability of this technique to treat antenna radiation on a large complex structure is demonstrated, as well as the improvement in memory storage and computation time when compared with the conventional method.
