ANTENNA DEVICE

WIPO Patent Application WO/2019/058932

A1

An antenna device comprising: a first dielectric layer; a planar patch antenna arranged on a first surface of the first dielectric layer and comprising an electrode section for electromagnetic coupling; a ground conductor plate arranged on a second surface on the opposite side to the first surface in the first dielectric layer and having a slot formed therein that constitutes a nonconductive section extending in a first direction and is at a position facing the electrode section; a second dielectric layer fixed to the ground conductor plate so as to face the first dielectric layer having the ground conductor plate interposed therebetween; and a linear power supply conductor formed in the second dielectric layer so as to face the ground conductor plate having the second dielectric layer interposed therebetween, having the tip thereof extending in a second direction intersecting the first direction when viewed from the normal direction of the patch antenna, and being arranged in a positional relationship so as to intersect the slot when viewed from the normal direction. The slot comprises: a first opening having a constant first width in the second direction; and a second opening connected to both ends of the first opening in the first direction and being widened more than the first width, in the vicinity of a section connecting to the first opening.
