Patent ID: 8779997

Claim:
A coaxial pylon antenna array, comprising; an input connection for connecting to a source of electromagnetic energy; a pylon section attached to said input connection, comprising an inner conductor surrounded by a tubular outer conductor, each with a longitudinal axis; with said outer conductor defining a plurality of slots parallel with the longitudinal axis and along one side of said outer conductor; a pair of rotational polarizers attached to an outer surface of said outer conductors adjacent to each slot and attached on opposite sides of said slot, with each of said rotational polarizers comprised of a mounting block or other electrically-conductive support attached to said outer conductor adjacent an edge of each of said slots, and said rotational polarizers further comprising a cylindrical or circular, square or rectangular cross-section conductor which extends from said mounting block or other electrically-conductive support, parallel with said slot edge, and spaced apart from said surface of said outer conductor, along an edge of each of said slots, with said polarizers configured to cause polarization and rotation of energy waves exiting said slot.
