Abstract

The calculation of the envelope correlation for a two antenna element system in terms of the system's scattering parameters is modified to include power losses. This new expression should reduce the complexity in predicting the spatial envelope correlation, and simplify antenna design where a low envelope correlation is required. This represents a major simplification with respect to the conventional use of the radiation field patterns of the antennas. The accuracy of the technique is illustrated by two examples.
