Abstract
A differential transmission transition interface is disclosed which can include first and a second buried conducting tracks providing respectively first and second differential couplings between a differential RF transmission output and a waveguide; the first buried conducting track extending over an opening of the waveguide to provide a first RF coupling element; and the second buried conducting track extending over the opening to provide a second RF coupling element. At least a portion of the first RF coupling element extends over the waveguide opening in a first angular direction; and at least a portion of the second RF coupling element extends over the waveguide opening in a second angular direction that is opposed to the first angular direction.
