RADIATING ELEMENTS HAVING DIPOLE ARMS WITH CLOAKED DIELECTRIC LOADING ELEMENTS AND BASE STATION ANTENNAS INCLUDING SUCH RADIATING ELEMENTS

A base station antenna includes a reflector, a first radiating element that extends forwardly from the reflector and that is configured to operate in a first frequency band, and a second radiating element that extends forwardly from the reflector and that is configured to operate in a second frequency band that is different from the first frequency band. The first radiating element comprises a first dipole radiator that has first and second dipole arms, a second dipole radiator that has third and fourth dipole arms, a first dielectric block positioned adjacent the first dipole arm, and a first metal pattern positioned between the first dielectric block and the reflector.
