| 摘要 |
A circularly polarized (CP) antenna comprised of at least one antenna bay. Each bay includes three individual CP antennas which are equally spaced circumferentially about a mast. Each individual CP antenna is comprised of a pair of crossed dipoles having drooping arms. The angle at which the arms droop is selected to provide good axial ratio at all positions in the vertical and horizontal patterns. Three reflectors extend radially from the mast and are arranged at circumferential positions intermediate the individual CP antennas. In one embodiment, six antenna bays of this type are provided at axially spaced positions along a single, common mast. An arrangement for feeding this multi-bay antenna is also disclosed.
