ABSTRACT:
An antenna comprising a ground plane having a base portion and a cylindrical obstruction that extends from the base. The obstruction is oriented such that its longitudinal axis is perpendicular to the base ground plane. The antenna also has a conducting transmission along the length of the exterior of the obstruction. A feedpoint located near the base ground plane transmits a voltage signal between the transmission element and the exterior of the obstruction. A short circuit is provided between the transmission element and the obstruction at a point distal to the feedpoint.
