Abstract: Base station antennas are provided. A base station antenna includes a reflector and radiating elements that are in rows and columns on the reflector. Each of the radiating elements extends forwardly from the reflector. Moreover, the base station antenna includes power dividers that are on a calibration board, or on a feed board, of the base station antenna.

Abstract: Base station antennas are provided. A base station antenna includes a reflector having a first surface and a second surface that is opposite the first surface. The antenna includes first and second feed boards having first and second integrated beamforming networks, respectively, on the first surface of the reflector. The antenna includes a first plurality of high-band radiating elements that extend forward from the first feed board. The antenna includes a second plurality of high-band radiating elements that extend forward from the second feed board. Moreover, the antenna includes a plurality of low-band radiating elements on the first surface of the reflector.

Abstract: A radiating element includes a four-post feed stalk, a first feed line capacitively coupled to first and third posts of the feed stalk, and a second feed line capacitively coupled to second and fourth posts of the feed stalk. A quad arrangement of folded dipole arms are provided, which are mounted on and capacitively coupled to distal ends of the first through fourth posts within the feed stalk. In addition, the folded dipole arms in the quad arrangement are capacitively loaded to each other by inter-arm metallization. This inter-arm metallization is configured to include a quad arrangement of radially-inwardly extending metal projections that respectively extend between corresponding pairs of the folded dipole arms.

Abstract: Base station antenna calibration boards are provided. A base station antenna calibration board includes directional couplers and radio frequency (RF) transmission lines that are coupled to the directional couplers, respectively. Moreover, a first pair of the directional couplers has a coupler section that is between and coupled to a first pair of the RF transmission lines and that has a non-rectangular interior shape. Related base station antennas are also provided.

Abstract: A cross-dipole radiating element includes a first antenna element that includes a first stalk and a first dipole arm and a second antenna element that includes a second stalk and a second dipole arm. The first dipole arm includes an inner dipole segment that extends along a first longitudinal axis and an outer dipole segment that extends along a different second longitudinal axis, and the second dipole arm includes an inner dipole segment that extends along a third longitudinal axis and an outer dipole segment that extends along a different fourth longitudinal axis. A distal end of the inner dipole segment of the first dipole arm merges with a base of the outer dipole segment of the first dipole arm, and a distal end of the inner dipole segment of the second dipole arm merges with a base of the outer dipole segment of the second dipole arm.
