Abstract:
A dual polarized multiband antenna comprising:a reflector;a first radiating element module having first dipole elements positioned at right angles to one another for transmitting and receiving electromagnetic radiation in a first frequency band range with two linear orthogonal polarizations, said first dipole elements being arranged in a dipole square and located in front of the reflector with the dipoles being aligned in an alignment of .+-.45.degree. with respect to a vertical, and a second radiating element module for transmitting and receiving electromagnetic radiation in a second frequency band range higher than the first frequency band range;said second radiating element module being arranged within the dipole square of the first radiating element module;said second radiating element module including dipole elements aligned orthogonally with respect to one another;said second dipole elements being aligned parallel or at right angles to said first dipole elements;the ratio of a mid-frequency of said second frequency band range to a mid-frequency of the first frequency band range being between 1.5 and 4.
