ABSTRACT:
A dual orthogonal inverted L near vertical incidence skywave antenna incls two orthogonal RF loop elements coupled to a ground plane. The first RF loop element is mounted in a first plane and has first feed and ground nodes. The second RF loop element is mounted in a second plane substantially orthogonal to said first plane, and has second feed and ground nodes. The first and second elements are feed from a center feed node and are coupled to the ground plane at different locations. An important performance characteristic of the antenna is that it has no nulls in its azimuth pattern.
