Abstract

In this paper, the design of a compact coaxial-type feed for luneberg lens antenna is presented. As an important part of the luneberg lens antenna system in satellite communication, this feed is designed to operate at multiple frequencies and polarizations. It consists of two parts: an inner circular horn and outer corrugated horn, which realizes the goal of receiving and transmitting signals from the same satellite. An inner circular waveguide loaded by dielectric rod operates in Ka-band and couple circular polarizations, Outer corrugated horn provides symmetrical pattern and low cross-polar for Ku-band, which operates in line polarization. All electromagnetic simulated results are presented to demonstrate the capabilities of the feed.
