Abstract
Systems and devices relating to dipole antennas. The beamwidth of a crossed dipole antenna is widened by providing a parasitic monopole antenna adjacent to the crossed dipole antenna. In one configuration, each arm of the crossed dipole antenna has, adjacent to it, a parasitic monopole antenna. In another configuration, the crossed dipole antenna is surrounded by a number of other crossed dipole antennas acting as parasitic monopole antenna elements. The center or primary crossed dipole antenna can be for low band signals while the secondary crossed dipole antennas are for high band signals.
