Abstract
A microwave antenna having an exponentially expanding horn of circular outlet cross-section. The inlet opening to the horn has a rectangular cross-section. In a transition region from the inlet opening up to the point at which the circular horn cross-section circumscribes the rectangular cross-section, each cross-section of the horn corresponds to the combination of the exponentially expanding circular cross-section and the rectangular cross-section.
