Abstract: A base station antenna includes a panel that has a ground plane, first and second arrays that have respective first and second sets of linearly arranged radiating elements mounted on the panel, and a decoupling unit positioned between a first radiating element of the first array and a first radiating element of the second array. The decoupling unit includes at least a first sidewall that faces the first radiating element of the first array, a second sidewall that faces the first radiating element of the second array and an internal cavity that is defined in the region between the sidewalls. The first and second sidewalls are electrically conductive and electrically connected to the ground plane.

Abstract: Base station antennas include first and second radio frequency ("RF") ports and a first antenna array that includes both first and second radiating elements. Each of the first radiating elements includes a first radiator that is connected to the first RF port that is configured to radiate at a first polarization and a second radiator that is connected to the second RF port that is configured to radiate at the first polarization. Each of the second radiating elements includes a first radiator that is connected to the first RF port that is configured to radiate at a second polarization that is different from the first polarization and a second radiator that is connected to the second RF port that is configured to radiate at the second polarization.

Abstract: A radiating element includes a feed stalk and first through fourth dipole arms. An outer segment of the first dipole arm and an outer segment of the second dipole arm are configured to together form a first radiating structure that radiates at a first polarization, an outer segment of the third dipole arm and an outer segment of the fourth dipole arm are configured to together form a second radiating structure that radiates at the first polarization, and first and second inner portions of each of the first through fourth dipole arms are configured to together form a third radiating structure that radiates at the first polarization when a first RF signal is fed to the radiating element.

Abstract: An antenna includes a box dipole radiating element, which is supported in front of a reflector. The box dipole radiating element has first through fourth feed ports, which extend adjacent first through fourth corners thereof. First through fourth pairs of slanted feed paths are also provided, which are coupled to the first through fourth feed ports. These first through fourth pairs of slanted feed paths extend rearwardly toward the reflector at first through fourth acute angles relative to respective first through fourth sides of the box dipole radiating element, so that: (i) the first and third pairs of slanted feed paths appear to criss-cross each other when a space between the box dipole radiating element and the reflector is viewed in a direction normal to the first side and parallel to the reflector; and (ii) the second and fourth pairs of slanted feed paths appear to criss-cross each other when the space is viewed in a direction normal to the second side and parallel to the reflector.
