Title:
ANTENNA
Document Type and Number:
WIPO Patent Application WO/2019/189005
Kind Code:
A1
Abstract:
The purpose of the present invention is to suppress dielectric loss when a signal wave is transmitted between a power feed wire and an antenna element through a slot. This antenna 21 is provided with: a dielectric substrate 28 having a recess 28b; a ground conductor layer 27 which is bonded to the dielectric substrate 28 by blocking the recess 28b and has slots 27a to 27d disposed inside the recess 28b; a dielectric layer 26 bonded to the ground conductor layer 27 on the opposite side of the dielectric substrate 28 with respect to the ground conductor layer 27; antenna elements 29a to 29d formed on the bottom 28d of the recess 28b at positions facing the slots 27a to 27d; and a power feed wire 24a which is formed on the opposite side of the ground conductor layer 27 with respect to the dielectric layer 26 and is electromagnetically coupled to the antenna elements 29a to 29d through the slots 27a to 27d.
