Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/195110
Kind Code:
A1
Abstract:
This antenna device is provided with: a ground plate (10), which is a plate-shaped conductor member; an opposing conductor plate (30), which is a plate-shaped conductor member disposed with a prescribed spacing from the ground plate, and which is provided with a power feed point that is electrically connected to a power feed line; and a short-circuiting portion (40) which is provided in a central region of the opposing conductor plate, and which electrically connects the opposing conductor plate and the ground plate. The configuration is such that parallel resonance occurs at a prescribed target frequency by employing an inductance provided by the short-circuiting portion, and electrostatic capacitance formed by the ground plate and the opposing conductor plate. The ground plate is disposed asymmetrically with respect to the opposing conductor plate.
