ADVANCED CONFORMAL ANTENNA WITH FOUR OMNIDIRECTIONAL BEAMS

摘要

A low profile, conformal, wideband (e.g., 0.6 to 5 Ghz) antenna assembly consists of four subarrays, each sub array consisting of four crossed bow tie elements. The sub arrays are disposed over a cavity. A beamforming circuit coupled to the sub- arrays, depending on configuration, provides two (2) or four (4) simultaneous orthogonal, omnidirectional beams. The assembly may be placed within or adjacent a metal vehicle roof of a vehicle.
