摘要： A circularly polarized microcell antenna (10) that requires only a single feed-line to radiate circularly polarized electromagnetic energy therefrom. The antenna (10) comprises a reflector box (14) having a bottom (15) and side walls (17) to which an electrical connector (20) is mounted. The center conductor (24) of the connector (20) is electrically connected to a conductor bar (22) upon which a first dipole assembly is mounted at a designated one-quarter wavelength location. The shell of the connector (20) is electrically connected to the reflector box (14) upon which a second dipole assembly is mounted at a designated one-quarter wavelength location. Each dipole assembly comprises a primary dipole arm (52) and a secondary dipole arm (68) which are electrically connected by a phasing loop that introduces a 90° phase shift between the primary dipole arm (52) and the secondary dipole arm (68). Thus, a single feed-line is capable of feeding both the primary and secondary dipoles so as to allow circularly polarized electromagnetic energy to radiate therefrom.
