Abstract
The design of a multifrequency feed system for the microwave radiometer for Ocean Sat-II satellite covering 18.7. 23.8 and co 36.5GHz frequency bands is reported. A groove discontinuity is introduced at the input of the corru gated hom to optimise amplitude taper and the symmetry of primary patterns at the highest frequency without affecting the performance at lower frequen cy bands. Computed and measured radiation patterns are compared at all the frequencies.
