We continue in this paper a comprehensive theory of antenna near fields inaugurated in Part
I. The concept of near-field streamlines is introduced using the Weyl expansion in which the
total field is decomposed into propagating and nonpropagating parts. This process involves
a breaking of the rotational symmetry of the scalar Greens function that originally facilitated
the derivation of the Weyl expansion. Such symmetry breaking is taken here to represent a
key to understanding the structure of the near fields and how antennas work in general. A …

We present in this paper a comprehensive theory of antenna near fields in two parts,
highlighting in particular the engineering perspective. Part I starts by providing a general
conceptual framework for the more detailed spectral theory to be developed in Part II. This
paper proceeds by proposing a general spatial description for the electromagnetic field in
the antenna exterior region based on an asymptotic interpretation of the Wilcox expansion.
This description is then extended by constructing the fields in the entire exterior domain by a …
