An effective method for antenna placement on platforms based on the reaction theorem

Simulations for antenna placement on large platforms are computational costly. We here suggest a very efficient method for antenna placement optimization of low-scattering antennas. The method utilizes the reaction theorem to calculate the mutual impedance between the antennas based on precomputed electromagnetic fields. The method needs only one full-platform simulation together with postprocessing of field data to estimate the coupling for all antenna positions in a given region. In the tested case, we see a speed-up with a factor of 2 000, compared to full-wave simulations of every antenna position to be evaluated.
