Abstract :
This paper presents a comparison the Eleven Antenna and the ETS-Lindgren quadridge horn in terms of their radiation performance as feeds for reflector antennas. They are both candidates for feeding future radio telescopes for Square Kilometer Array and VLBI2010. The comparison is done by processing measured radiation field functions and input reflection coefficients of both antennas to determine expected reflector antenna performance.
