Abstract :
A triple-frequency feed for a proposed satellite mission is discussed. The realized feed combines good radiation characteristics with a good match to free space over a large bandwidth in each of the three frequency bands (around 1.6, 5 and 22 GHz). Use has been made of a coaxial matching network, realized using an analytical model. Overall performance parameters for the feed combined with a parabolic reflector are presented.<>
