Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/112357
Kind Code:
A1
Abstract:
In the present invention, an antenna device is provided with the following: a dielectric substrate (301); a feed element (304) formed on top of the dielectric substrate (301) and having one radiation direction; a front-side array (305) that includes a plurality of parasitic elements formed in a region that is in the radiation direction with respect to the feed element (304) on the dielectric substrate (301); and at least one side array (306, 307) that includes a plurality of parasitic elements formed in at least one region that is in a direction other than the radiation direction with respect to the feed element (304) on the dielectric substrate (301). The plurality of parasitic elements of the front-side array (305) constitute a plurality of front-side sub-arrays that each include a plurality of parasitic elements aligned along the radiation direction. The plurality of front-side sub-arrays are disposed parallel to each other in the radiation direction, such that the parasitic elements of two front-side sub-arrays adjacent to each other are close to each other. The plurality of parasitic elements of the side arrays (306, 307) are essentially aligned along the radiation direction.
