CLOAKED RADIATING ELEMENTS HAVING ASYMMETRIC DIPOLE RADIATORS AND MULTIBAND BASE STATION ANTENNAS INCLUDING SUCH RADIATING ELEMENTS

摘要

A dual-polarized radiating element includes a first dipole radiator that has a first dipole arm that generally extends along a first axis and a second dipole arm that generally extends along a second axis that is different from the first axis, and a second dipole radiator that has a third dipole arm that generally extends along the first axis and a fourth dipole arm that generally extends along a third axis that is different from the first axis. At least one of the first through fourth dipole arms may be a cloaked dipole arm that include inductive elements that are configured to suppress currents in a higher frequency band.
