Fields of a horizontal wire antenna over a layered half-space

A previous analysis for a horizontal loop antenna is extended to deal with a horizontal wire antenna located over a layered half-space. As before, the exact solution so obtained is reduced to known special cases for the T.M. (transverse magnetic) and T.E. (transverse electric) radiated fields. These expressions are valid for zero or small heights above the air/ground interface. The application to a flat lying butterfly antenna, as a source, is also outlined.
