Abstract
The dual frequency antenna element has electromagnetically resonant structure with plural attached current conductors each communicating on a different frequency band and producing a circularly polarized radiation pattern with respect to a propagation direction. A pattern shaper element fashioned using first and second conductive discs is positioned within the radiation pattern in alignment with the propagation direction. The discs are secured in a first spaced relation to each other and in a second spaced relation to the dual frequency antenna element. The respective disc surface areas, and the first and second spaced relations are cooperatively configured to passively modify the radiation pattern of the dual frequency antenna element to produce dual frequency band coverage of approximately 60 degrees centered about the longitudinal axis while substantially blocking coverage at 90 degrees to the longitudinal axis.
