This paper describes the preliminary design and construction of a development model of antennas proposed to be installed on satellites as microwave radiometers (MWR, Microwave Water Radiometer), at K and Ka bands. These instruments will be dedicated to study the global water cycle while analyzing geophysical parameters. Several antennas have been studied between the 23.8 GHz and 36.5 GHz frequencies to obtain a design which fulfills the technical requirements. An optimal result was obtained with multiple beam torus reflector antennas with an asymmetric feed array. The measured results are shown.
