A new telescope feed system

A new telescope feed system at millimeter wavelength is described. This system is designed to operate at 100 GHz. The element antennas are offset parabolic reflectors with a diameter of 1 meter and a f/D ratio of 100. The Gaussian beam technique is used for wideband feed design. A major advantage of the Gaussian technique is the simplicity of the Gaussian formula. This new 100 GHz radiotelescope feed system will result in the construction of twenty feeds based on this design concept by the beginning of 1999.
