PATCH ANTENNA
Document Type and Number:
WIPO Patent Application WO/2015/083457
Kind Code:
A1
Abstract:
In the present invention, a surface layer conductor plate that is provided with an opening is disposed on a first surface of a dielectric substrate. A radiation electrode is disposed on the inner side of the opening on the first surface of the dielectric substrate. A ground conductor plate is disposed on a second surface that is on the opposite side from the first surface of the dielectric substrate. An interlayer connection member is disposed so as to surround the opening, in plan view. The interlayer connection member electrically connects the surface layer conductor plate to the ground conductor plate, and demarcates a cavity that generates electromagnetic wave resonance. A reactance element imparts a reactance component to the impedance indicated by the side walls of the cavity with respect to the electromagnetic waves that propagate within the cavity.
