DUAL-FREQUENCY CO-APERTURE ARRAY ANTENNA AND COMMUNICATIONS DEVICE

摘要

The present invention relates to the field of communications technologies. Disclosed are a dual-frequency co-aperture array antenna and a communications device. The antenna comprises a first band antenna module and a second band antenna module. The first band antenna module comprises multiple first band antenna units. The second band antenna module comprises at least one second band antenna unit. The first band antenna unit is a tablet antenna unit. The first band antenna units are arranged in a linear array manner, and a main lobe radiation direction is perpendicular to a patch. The array formed by the first band antenna units has insertion gaps. The second band antenna unit is a planar end-fire antenna unit. Patches of the second band antenna units are perpendicular to patches of the first band antenna unit, and are inserted in corresponding insertion gaps. The second band antenna units are arranged in a linear array manner, and a main lobe radiation direction is perpendicular to a patch of the first band antenna unit. The foregoing dual-frequency co-aperture array antenna has flexible arrangement, low dependence on band ratios of two operating bands, and high applicability.
