Abstract :
New remote sensing applications demand antennas with high beam efficiency and low cross polarization. These goals may be achieved by using corrugated feed horns illuminating conventional parabolic reflectors. The effects of reducing the number and thickness of corrugation are investigated. It is shown that with careful choice of these parameters at the limits, relatively light weight corrugation horns with comparable performance can be designed. A new version of a corrugated horn feed was proposed for spaceborne radar application and its performance investigated.
