A dual-polarized multiband antenna includes first and second radiating element modules having first and second dipole elements. First dipole elements are positioned at right angles to one another to transmit and/or receive radiation in the first frequency band range with two linear orthogonal polarizations. The dipole elements form a dipole square. The second radiating element module transmits or receives radiation in a second frequency band range higher than the first frequency band range. The second module has dipole elements orthogonally related to one another and aligned parallel or at right angles to the first dipoled elements. The second dipoles are arranged in a cruciform.
