Claim Text:
1. An unbalanced antenna, comprising: a dielectric substrate having an upper side, a lower side, and an outward edge; a first and a second spiraling conductive radiator arm mounted on said dielectric substrate, wherein said first and second spiraling conductive radiator arms originate from the center of said dielectric substrate, wherein said first and second spiraling conductive radiator arms are resistively terminated, wherein each of said first and second spiraling conductive radiator arms are mounted on said lower side of said dielectric substrate; a single component flat top cone with cylinder sidewall, said single component flat top cone with cylinder sidewall having one single flat upper portion parallel with said dielectric substrate, said single flat upper portion transitioning to a single flat lower portion parallel with said dielectric substrate, said single flat lower portion transitioning to said cylinder sidewall, said cylinder sidewall having an outer surface, said cylinder sidewall of said single component flat top cone is attached to said lower side of said dielectric substrate wherein said outer surface of said cylinder sidewall is not vertically aligned with said outward edge of said dielectric substrate, said attachment forming a scalable feed cavity proximate said lower side of said dielectric substrate and defined by said single component flat top cone with cylinder sidewall, said single component flat top cone with cylinder sidewall having a substantially-uniform cross-sectional thickness, wherein said single component flat top cone is hollow; and a magic-T signal combiner electrically connected with said first and second spiraling conductive radiator arms by a coaxial stripline feed comprising two coaxial transmission lines, wherein said magic-T signal combiner is configured to combine power signals and transmit said combined power signals to each of said first and second spiraling conductive radiator arms, wherein each of said coaxial transmission lines is connected to only one of spiraling conductive radiator arms.
