Abstract: A base station antenna that extends along a first longitudinal axis includes a first array configured to emit electromagnetic radiation. The first array includes a first column of radiating elements, the first column including a first radiating element and a pair of second radiating elements. The first radiating element is a cross dipole radiating element and the pair of second radiating elements includes a pair of second radiating elements that are disposed facing each other on both sides of the first longitudinal axis, where each of the second radiating elements includes first and second radiating arms that extend respectively in opposite directions substantially along the first longitudinal axis, and a third radiating arm that extends toward the first longitudinal axis substantially perpendicular to the first and second radiating arms.

Abstract: A low frequency band radiating element for a multiple frequency band cellular base station antenna comprises a dipole arm including a radiating portion and a first coupling portion and a dipole leg that includes a leg and a second coupling portion located at one end of the leg. The first coupling portion is removably connected to the second coupling portion. A thin metal sheet with a suitable electrical performance can be selected for the dipole arm, and a thick metal plate can be selected for a dipole leg so as to achieve mechanical strength.

Abstract: Radiating elements, antenna assemblies, and base station antennas including the same. For example, a radiating element is provided that includes a feed stalk and a radiator mounted on the feed stalk. The feed stalk includes a dielectric substrate, a first metal pattern printed on a first major surface of the dielectric substrate, and a second metal pattern printed on a second major surface of the dielectric substrate that is opposite the first major surface. The first metal pattern includes a first feed transmission line and a first feed welding region electrically connected to the first feed transmission line. The second metal pattern includes a second feed welding region electrically connected to the first feed welding region.

Abstract: Antennas comprise a reflector and first and second arrays of first radiating elements mounted on the reflector. The antenna further comprises a parasitic element including a metal ring, where the metal ring of the parasitic element is arranged between a first radiating element of the first array and a first radiating element of the second array. The antenna can improve the isolation between adjacent arrays, thereby improving the radiation patterns generated by the arrays.
