Abstract:
1. A system for transitioning free-space-propagating electromagnetic energy interfaced using an array of elongate elements to transverse electromagnetic-mode propagating energy, said system comprising: a dielectric substrate; an array of electrically-conductive pads, said pads arranged in spaced-apart fashion on said substrate, each of said pads adapted to be substantially covered by and electrically coupled to one of the elongate elements at a base thereof, wherein portions of each of said pads not covered by the base are exposed with each of said portions comprising a trapezoid shape; and a plurality of baluns, each of said baluns extending through said substrate with one end thereof disposed between said portions of two adjacent ones of said pads, each of said baluns defined by a dielectric material sandwiched between two identical-width electrical conductors, each of said electrical conductors electrically coupled to one of said portions of said two adjacent ones of said pads.
