An X-band horn antenna couples energy between a waveguide and
free space. An important function of the Ka-band horn antenna is impedance matching.
A Ka-band horn antenna is usually
optimised to work in the Ka band band. For example,
in a satellite antenna, a Ka-band horn antenna is
often placed at the focus of a parabolic antenna. A
different horn antenna would usually be used in each of
the X band, C band, Ku band and Ka band.
