DUAL-POLARIZED DIPOLE ANTENNA

The invention relates to a dual-polarized dipole antenna which consists of several separate dipoles. Said dipoles are preferably arranged in front of a reflector (33) and form a dipole square when viewed from above, whereby each dipole (111-114) is supplied with current via a symmetrical line (115-1...

Summary:The invention relates to a dual-polarized dipole antenna which consists of several separate dipoles. Said dipoles are preferably arranged in front of a reflector (33) and form a dipole square when viewed from above, whereby each dipole (111-114) is supplied with current via a symmetrical line (115-118). The invention is characterized by the following features: The dual-polarized dipole antenna transmits electrical radiation in a polarization at an angle of +45~ or -45~ in relation to the constructively predetermined alignment of the dipoles (111-114); the ends of the symmetrical or approximately symmetrical lines which lead to the respective dipole halves (111a to 114b) are interconnected in such a manner that the corresponding line halves (115a to 118b) of the adjacent dipole halves (114b and 111a; 111b and 112a; 112b and 113a; 113b and 114a) which are vertical in relation to one another are electrically connected; and the supply of electric power to the diametrically opposite dipole halves results for a first polarization and decouples a second polarization which is orthogonal thereto.
