Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/134819
Kind Code:
A1
Abstract:
Provided is an antenna device, comprising: a ground conductor (1) whereupon slots (2a - 2g) for radiating electromagnetic waves are formed; a ground conductor (3) in which cavities (4) are formed in positions facing the slots (2a - 2g) which are formed in the ground conductor (1) and which are hollowed out in a direction away from the ground conductor (1); and center conductors (5a, 5b, 6a - 6c, 7a, 7b) which are positioned between the ground conductor (1) and the ground conductor (3) in positions which overlap with the slots (2a - 2g). The positions of the center conductors (5a, 5b, 6a - 6c, 7a, 7b) are made nearer to the ground conductor (1) side than to the ground conductor (3).
