Abstract

Dual-polarized dipole radiator which comprises a plurality of individual dipoles which are preferably arranged upstream of a reflector (33) and form a dipole square structurally in top view, each dipole (111-114) being fed by means of a symmetrical line (115-118), characterized by the following further features: PA1 the dual-polarized dipole radiator radiates electrically in a polarization at an angle of +45.degree. or -45.degree. to the structurally prescribed alignment of the dipoles (111-114); PA1 the end of the symmetrical or substantially or approximately symmetrical lines leading to the respective dipole halves (111a to 114b) are connected up in such a way that the corresponding line halves (115a to 118b) of the adjacent, mutually perpendicular dipole halves (114b and 111a; 111b and 112a; 112b and 113a; 113b and 114a) are always electrically connected; and PA1 the electric feeding of the respectively diametrically opposite dipole halves is performed in a decoupled fashion for a first polarization and a second polarization orthogonal thereto.
