An antenna apparatus includes: (a) A radial waveguide parallel with a reference plane and having a first conductive element in parallel spaced relation with a second conductive element. The radial waveguide has a first signal coupling locus for coupling signals with a host unit and a plurality of second signal coupling loci. The radial waveguide distributes signals between the first signal coupling locus and the second signal coupling loci. (b) Signal coupling elements, each presenting a respective signal coupling path for effecting signal coupling association with a respective second signal coupling locus. Each signal coupling path is perpendicular with the reference plane. (c) Antenna elements, each associated with a signal coupling element, each a polygonal element parallel with the reference plane. The radial waveguide element, the signal coupling elements and the antenna elements cooperate to transfer electromagnetic signals between the host unit and a medium adjacent to the antenna elements.
