FLARED MICROWAVE FEED HORNS AND WAVEGUIDE TRANSITIONS

摘要

An overmoded waveguide transition comprises a flared waveguide (10) having predetermined transverse cross-sections at its opposite ends. Adjacent at least one end of waveguide (10) a section (10a) of the waveguide (10) is defined by the equation

where a and b are constants, r is the transverse dimension from the longitudinal axis (15) of the waveguide (10) to the side wall of the section (10a), l is the axial distance along the section (10a) measured from the pertaining end of the waveguide (10) and the exponent p has a value which is greater than 2. Preferably exponent p has a value within the range 2.5 to about 7.
