1. A dual-polarized radiator for a mobile communication antenna, comprising:
four radiator segments; and
a reflector, wherein
the four radiator segments are arranged on the reflector,
each radiator segment is arranged at a 90° rotation relative to its two neighbouring radiator segments so that the four radiator segments form a square and enclose a receiving area,
each radiator segment comprises a minor radiating surface having a first end and a second end,
each minor radiating surface is arranged substantially parallel to and spaced apart from the reflector,
the minor radiating surface of each radiator segment extends in a longitudinal direction and in a transverse direction, wherein the extension in the longitudinal direction being larger than the extension in the transverse direction,
each radiator segment comprises a feeding assembly,
each radiator segment comprises a first and a second main radiating surface,
for each radiator segment, the first main radiating surface of the radiator segment is arranged in the area of the first end of the minor radiating surface and runs in the direction of the reflector,
for each radiator segment, the second main radiating surface of the radiator segment is arranged in the area of the second end of the minor radiating surface and runs in the direction of the reflector,
for each radiator segment, the first main radiating surface of the radiator segment protrudes beyond the first end of the minor radiating surface in the longitudinal direction of the minor radiating surface, and
for each radiator segment, the second main radiating surface of the radiator segment protrudes beyond the second end of the minor radiating surface in the longitudinal direction of the minor radiating surface.
