Abstract
A bicone antenna and methods for manufacture therefor can include a feed portion, a top section and a bottom section that can be centered on a vertical axis. The top section and bottom sections can each have a respective conical surface, which can extend radially outward from the vertical axis at an inner portion at a constant angle θ1 with respect to a horizontal antenna axis of the antenna. For both sections, the inner portion can merge into an outer portion that can have a curved surface, with the curved surface extending radially outward from the conical surface so that the curved surface has a logarithmic profile when viewed in side profile. The above structure can allow for a multi-directional antenna with a minimum of moving parts, which can be easily manufactured, including by additive manufacturing techniques.
