Microwave Energy Transmission System For Around-the-mast Applications

Abstract

A microwave energy transmission system for coupling a stationary waveguide to a rotating waveguide including a transition coupling assembly comprising a plurality of equal length transmission lines having their opposite ends terminating in annular patterns defining equidistantly, circumferentially spaced regions of maximum coupling, and a pair of rotatable horns having flared apertures sweeping circular paths in gapped registry with the annular patterns and spanning, at any instant, a plurality of said regions.
