Abstract: An antenna is provided as a dipole class radiator with a first bell-shaped element and a second bell-shaped element that extend from a feed gap and are mirror images to each other. Each of the elements has a contour with a combination of curvilinear segments sized to an overall impedance for needed radiation beam pattern properties. In detail, the feed gap with a feed port is between small spherical feed hubs with a larger spherical boss for each element extending away from each feed hub and the feed gap. A frusto-conical section and an adjacent cylindrical section extend from the larger spherical boss for each antenna. The antenna is capable of fitting within a cylindrical shell whose surface area-to-volume ratio is a minimum. The radiation field produced by the antenna is omnidirectional in a horizontal plane. The antenna occupies a minimum surface area-to-volume ratio; thereby, requiring less material.
