Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/066419
Kind Code:
A1
Abstract:
An antenna device comprises: a ground plate (10) that is a plate-shaped conductor member; a patch part (20) that is a plate-shaped conductor member installed so as to oppose the ground plate with a predetermined distance therebetween; a short-circuiting part (60) that is a conductor member electrically connecting the patch part with the ground plate; and an additional conductor (30) that is a plate-shaped conductor member installed so as to oppose the patch part with a predetermined distance therebetween, on the side of the patch part on which the ground plate is not located. The antenna device exhibits a parallel resonance by use of an inductance of the short-circuiting part, a capacitance formed by the ground plate and the patch part, and a capacitance formed by the patch part and the additional conductor.
