Abstract: A patch radiating element that includes a feeder pillar and a patch radiator mounted on the feeder pillar. The patch radiator includes a first patch portion extending in a first direction and a second patch portion extending from an outer end portion of the first patch portion in a second direction. The second direction is different from the first direction. As a result, a space interval between adjacent patch radiating elements can be increased, thereby improving the isolation between the adjacent patch radiating elements so that beamforming of an antenna can be optimized.

Abstract: A radiator assembly for a base station antenna includes two dipoles arranged in a cross-over manner, each dipole including two dipole arms, and two feeding lines, each feeding line being associated with a respective one of the dipoles. Each dipole arm is integrally formed of sheet metal, and includes a radiating surface and a leg projecting from the radiating surface at an angle with the radiating surface, where the leg is electrically grounded.

Abstract: A base station antenna includes a column of radiating elements comprising first and second sets of radiating elements, each radiating element being configured to operate in a first frequency band that has first and second sub-bands. The second set of radiating elements is located above and/or below the first set of radiating elements. The antenna further includes a feeding assembly that is configured to feed first RF signals that are in the first sub-band and second RF signals that are in the second sub-band to the column of radiating elements, where the feeding assembly is configured to partially attenuate sub-components of the second RF signals that are fed to the second set of radiating elements more than sub-components of the first RF signals that are fed to the second set of radiating elements.

Abstract: Base station antennas include a reflector, a first array of cross-polarized radiating elements that are mounted to extend forwardly from the reflector, and a parasitic assembly. The parasitic assembly includes a base that is mounted on the reflector, a horizontal component shaping element, and a forwardly projecting member that projects forwardly from the base that is coupled between the base and the horizontal component shaping element. The horizontal component shaping element may extend substantially parallel to a plane defined by the reflector and may include a proximate side that is directly connected to the forwardly projecting member and a distal side that is opposite the proximate side. The distal side of is only electrically connected to the reflector through the proximate side.
