Abstract
An antenna including a common ground plane, a first set of n approximately resonant elements with a length l2 and a second set of n approximately resonant elements with a length l1. The first set of n approximately resonant elements are wound to form a first helix with an initial diameter d2 and a height h2. The second set of n approximately resonant elements are wound in the opposite direction to the first set of n approximately resonant elements to form a second helix. The second helix is centrally disposed within the first helix, and has an initial diameter d1 and a height h1 where d1 is less than d2 and h1 is greater than h2.
