ABSTRACT:
A wideband multi-mode antenna having low VSWR operating characteristics. The antenna element is formed from a right-triangularly shaped piece of conductive material, which is rolled along the base dimension. Operational characteristics may be modified by spacing the antenna element from a ground plane using dielectric spacers, and the antenna element may be shorted to the ground plane.
