Abstract
The present invention is directed to a monopole/dipole symmetric radiator structure that includes a symmetric planar radiator. When the symmetric radiator 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, the symmetric planar radiator has an outer edge that is bilaterally symmetrical. In another embodiment, the outer edge of the symmetric planar radiator is bilaterally symmetric and a closed inner edge of the radiator that defines a void is also bilaterally symmetric.
