Abstract:

A propagating mode transition system provides a transition from a free-space-propagating electromagnetic energy field, which is partitioned by an array of elongate elements, to a transverse electromagnetic-mode propagating energy field in a transmission line. Electrically-conductive pads are disposed on a substrate with the pads being arranged in spaced-apart fashion. Each pad is substantially covered by and electrically coupled to one of the elongate elements at a base thereof such that portions of each pad not covered by the base are exposed. Each of a plurality of transmission line baluns extends through the substrate with one end thereof disposed between the exposed portions of two adjacent pads. Each balun includes two identical-width electrical conductors with each conductor being electrically coupled to one of the exposed portions.
