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