Abstract
A fringe-effect vault antenna includes a communications vault having a non-conductive cover disposed substantially at ground level. An antenna element is positioned in the communications vault. A metallic reflector has an edge, positioned substantially parallel to the ground, where the metallic reflector and the edge are configured to cause an edge diffraction, or “fringe-effect” upon the RF fields of the antenna to cause those RF fields to diffract in a direction toward the ground.
