Claim Text:
1. A dual-polarized, omnidirectional antenna comprising: at least first, second and third separate sector antennas which are positioned mutually offset in the circumferential direction about a central axis, each of the first, second and third sector antennas comprising at least one respective antenna gap comprising an associated respective reflector, which is arranged at least in part in an associated reflector plane, each associated reflector having a respective wall, at least one dual-polarized radiator being arranged in the antenna gap in front of the reflectors, and the sector antennas being additionally arranged mutually offset along the central axis thereof, the sector antennas being arranged in such a way that, in an axial view along the central axis, the first, second and third sector antenna reflector walls, arranged in respective reflector planes, of the first, second and third sector antenna reflectors intersect a supply, which is coupled to the associated sector antenna; wherein the reflector walls or the reflector planes are positioned parallel to the central axis and spaced to the central axis such that the distance between the reflector plane of a sector antenna and the central axis is smaller than 15% of the gap width of a respective antenna gap; and wherein the central axis extends on a side of a said reflector plane on which the dual-polarized radiators are positioned.
