摘要： Antennas that can transceive signals in an elliptically-polarized, omni-directional manner are described. In an example embodiment, an antenna comprises two elements proximally located to each other at a predetermined distance, such that two orthogonally- polarized omni-directional electromagnetic waves are tranceived. In a further example, the two elements are supported by an internal printed circuit, the printed circuit including conductors configured to supply a feed to the elements, which may be contained within a radome. Alternate embodiments comprise a plurality of elements of varying lengths.

摘要： Antennas that can transceive signals in a horizontally-polarized, omni-directional manner are described. In an example embodiment, an antenna comprises a spiraling surface having a spiral cross-section, the surface forming an internal cavity, an internal channel to the external surface, and an internal wall common to the cavity and the channel. Further, an example embodiment comprises a longitudinal opening allowing access to the cavity and the channel by a transmission feed line. Alternate embodiments comprise various cross-sectional configurations, and may also comprise a radome at least partially surrounding the antenna spiraling surface and supporting structure.
