Provided are examples of circularly polarized omni-directional antennas which contain an equal number of driven radiators and parasitic radiators spaced radially around a central axis which in which the driven elements are fed from a central feed system. This type of antenna allows for a compact size with higher axial ratio than other designs. In one aspect, an antenna comprises 2 or more elements shaped as a single curve in a cylindrical structure. In another aspect, the antenna may take on an angular form such as a square or a hexagon in which the elements may contain multiple angles. The antenna may be contained within a non-conductive enclosure and may contain a transmission line such as a coaxial cable.
