Abstract
A spiral antenna apparatus, which may comprise an antenna element disposed in two spiral arms in a vertical zigzag pattern. The apparatus may comprise an electromagnetic band gap cavity comprising: a ground plane, one or more layers of conductive patches, at least one pillar extending between the ground plane and a top layer of the one or more layers, and low dielectric foam disposed to fill gaps between the ground plane and the one or more layers and to fill gaps between the one or more layers. The apparatus may comprise a corrugated radio frequency choke disposed within the electromagnetic band gap cavity. At least one of the antenna element, the balun element, the electromagnetic band gap cavity, and the radio frequency choke may be fabricated using additive manufacturing.
