Abstract
The envelope correlation for a two-element antenna
array may be calculated using the antenna radiation fields, or
more simply from the scattering parameters of the system. The
use of scattering parameters provides a major simplification over
the direct use of field data. In this paper we propose a
modification of the scattering parameter method which also
includes the antenna losses. This approach has the advantage of
simplifying the antenna design process, especially when low
envelope correlations are needed. It also offers a better
prediction of the spatial envelope correlation, and a good
framework for understanding the effects of the mutual coupling.
The accuracy of this proposed method is illustrated by two
examples.
