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 &#x3b8;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.

A lens apparatus for improving antenna performance, the apparatus involving a lens configured to at least one of focus, refocus, and refract electromagnetic energy for constructively adding gain in a far-field, the lens configured to operably couple with an antenna, whereby electromagnetic energy is omnidirectionally concentrated, whereby antenna gain and directivity are improved, whereby antenna efficiency and antenna frequency range are maintained, and whereby antenna complexity is minimized.
