Abstract

A dual-polarized crossed dipole (1) comprises a first and a second dipole antenna element (2, 3). Each dipole antenna element (2, 3) comprises two dipole halves (2a, 2b, 3a, 3b), each having an earth connector (4, 8), a signal connector (6, 10), a dipole earth wing (5, 9) and a dipole signal wing (7, 11). The signal connector (6) of the first dipole antenna element (2) runs parallel to the earth connector (4) of the first dipole antenna element (2), and the signal connector (10) of the second dipole antenna element (3) runs parallel to the earth connector (8) of the second dipole antenna element (3). The dipole signal wing (7) and the dipole earth wing (5) of the first dipole antenna element (2) run in opposite directions. The same applies to the dipole signal wing (11) and the dipole earth wing (9) of the second dipole antenna element (3). Each dipole half (2a, 2b, 3a, 3b) is of single-part design in each case. The dipole signal wing (11) of the second dipole antenna element (3) passes through beneath the dipole signal wing (7) of the first dipole antenna element (2), or the dipole earth wing (9) of the second dipole antenna element (3) passes through beneath the dipole earth wing…
