1. A dual polarized dipole radiator which radiates in two polarization planes (P1, P2) located perpendicularly or substantially perpendicularly to one another,
the dual polarized dipole radiator being structurally formed in the manner of a dipole square having four sides,
each side of the dipole radiator formed in the manner of a dipole square comprising between two corner points two dipole components which, in plan view, are oriented at least approximately in the axial extension,
the polarization planes (P1, P2) passing, in each case, through an opposing pair of corner points,
two respective dipole components extending toward a common corner point being held via two feed arms and supplied with electricity, at a feed point provided on the respective dipole component, opposing an associated corner region,
the two respective feed arms, which lead to two dipole components provided on a side of the radiator at the respective feed points, being arranged substantially in parallel,
the respective dipole components extending toward a common corner region and the feed arms connected thereto, each feed arm extending at least substantially perpendicularly to the associated dipole component, and each connected to a support portion extending transversely and perpendicularly to a radiation plane E, two respective adjacent support portions each forming between them a balun with a slot,
the dual polarized dipole radiator comprising:
a strip and/or board material, the dual polarized dipole radiator being constructed in one piece from said strip and/or board material, and
individual portions of the dual polarized dipole radiator, including the dipole components, the feed arms, the support portions forming a balun and an associated base connecting the support portions, being connected to one another by bending and/or tilting and/or folding lines formed in the strip and/or board material.
