Descripción
The literature on horn antennas dedicated to radio astronomy and
satellite communications applications is very extensive and at times
disjointed, relevant contributions being distributed as far back as from
the 60's until the present today. This work combines a compact but
complete review of the different theories, methodologies and techniques
used to describe corrugations and metamaterials in their application to
feedhorns used in radio astronomy and satellite communications along
with some new work to help explain the theory in a more practical way.
Starting with the hybrid-mode condition firstly corrugated horns are
explained describing soft and hard boundaries and also the theory from a
plasmonic optics point of view. Following this the use of metamaterials
in order to design horn antennas with quasi-null cross-polarization and
low E-Plane sidelobes level over an ultra-wideband is described. The
objective of this work is to help to ease the learning curve of the post
graduate students and young professionals dedicated to these tasks, and
try to inspire the work of the senior professionals toward a new
direction and approach.
