Abstract :
Effective design of complex feeds for satellite antennas requires full-wave optimizations of nonconcentric, coupled, circular and coaxial apertures. Formulas for the mutual coupling between nonconcentric circular and coaxial apertures on a flange plane are derived. A network representation for a fairly general geometry is introduced and tested against published and measured data.
