MULTI-BAND BASE STATION ANTENNAS HAVING CROSSED-DIPOLE RADIATING ELEMENTS WITH GENERALLY OVAL OR RECTANGULARLY SHAPED DIPOLE ARMS AND/OR COMMON MODE RESONANCE REDUCTION FILTERS

摘要

A dual-polarized radiating element for a base station antenna includes a first dipole that extends along a first axis, the first dipole including a first dipole arm and a second dipole arm and a second dipole that extends along a second axis, the second dipole including a third dipole arm and a fourth dipole arm and the second axis being generally perpendicular to the first axis, where each of the first through fourth dipole arms has first and second spaced-apart conductive segments that together form a generally oval shape.
