Analysis and optimization of multi-port antennas by using circuit simulation and embedded element patterns from full-wave simulation

A method for efficiently analyzing and optimizing multi-port antennas based on the use of a port response matrix and embedded element patterns has been presented. This has been implemented in software which uses data from commercial full-wave EM codes and communicates with a circuit simulator for fast evaluation of antenna parameters for arbitrary port loadings. The method is especially useful for optimization which was demonstrated by a simple example.
