Abstract :
The various design techniques used for beam waveguide (BWG) feed systems are described. These include the use of Gaussian beam, Geometrical Optics, and Physical Optics design techniques for gain and efficiency and the waveguide modes theory for noise temperature determination. Examples illustrating the advantages, disadvantages and range of applicability of each design technique are given. Included are comparisons of computed and measured results
