The antenna system for the multi-frequency imaging microwave radiometer: M.I.M.R

Alenia Spazio is the prime contractor for the Multifrequency Imaging Microwave Radiometer, MIMR, which is an instrument proposed and under the responsibility of the European Space Agency. In the frame of its responsibility as prime contractor, Alenia Spazio has established the radiometer antenna electrical design and carried out the related breadboarding activity. The paper describes the MIMR electrical design of the antenna system composed of an instrument antenna and a cold calibration reflector, both illuminated by 9 feeds at 6 different frequencies. Short accounts are also given of simulation and test activity.
