Abstract
The present invention is directed to a monopole/dipole asymmetric radiator structure that includes an asymmetric planar radiator. When the asymmetric is part of an operative monopole or dipole antenna, the antenna exhibits a wide or broad bandwidth, a VSWR of less than about 3:1, a relatively constant gain perpendicular or broad-side to the plane of the radiator, and is vertically polarized. In one embodiment, asymmetric planar radiator has an outer edge that is bilaterally asymmetrical. In another embodiment, the outer edge of the asymmetric planar radiator is symmetric and a closed inner edge of the radiator that defines a void is bilaterally asymmetric.
