Abstract
A multi band antenna feed, for supporting multiple frequency bands, is coupled to a reflector and includes a cylindrical core waveguide and at least three coaxial cylinders, encircling said cylindrical core waveguide and forming at least three coaxial waveguides, bounded between pairs of consecutive coaxial cylinders. The cylindrical core waveguide and the at least three coaxial waveguides provide a pair of sum and difference radiation patterns, for each frequency band: a C-band, an S-band and an L-band.
