Abstract:
1. An antenna structure comprising: an electrically non-conductive support structure; mounted on said support structure, a base station antenna comprising at least one radiator supported adjacent a first ground plane, said at least one radiator configured to transmit or receive signals in a first frequency range and to develop a main beam substantially wider in azimuth than in elevation; mounted on said support structure and spaced elevationally above or below said base station antenna, an auxiliary antenna comprising at least one radiator supported adjacent a second ground plane isolated from said first ground plane, said auxiliary antenna configured to transmit or receive signals in a second frequency range overlapping said first frequency range and to develop an auxiliary beam at least partially overlapping said main beam azimuthally; and a radio frequency energy suppressor disposed between said base station and auxiliary antennas.
