Title:
ANTENNA DEVICE, WIRELESS COMMUNICATION DEVICE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/133065
Kind Code:
A1
Abstract:
An antenna device according to the present disclosure is provided with a first dielectric substrate, a second dielectric substrate, a driven element that is formed on the first dielectric substrate and has a single radiation direction, and a front array including a plurality of parasitic elements formed in a first region on the second dielectric substrate. The second dielectric substrate is fixed in relation to the first dielectric substrate so that the parasitic elements of the front array are positioned in the radiation direction when viewed from the driven element. The plurality of parasitic elements of the front array configure a plurality of front subarrays each including a plurality of parasitic elements aligned along the radiation direction. The plurality of front subarrays are provided so as to be parallel to each other in the radiation direction so that the parasitic elements of two adjacent front subarrays are close to each other.
