Base station antenna and multiband base station antenna

摘要

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.
