Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/150817
Kind Code:
A1
Abstract:
In a substrate including a dielectric plate and a conductive film which is formed on both faces of the dielectric plate, a first notch which faces from a portion of a first edge toward the inner side is formed in the conductive film of both faces of the substrate. A first radiation electrode is connected to the conductive film in a first point upon an external circumference line of the first notch. A first reflection plate is positioned in a location further away than the first point from the first edge toward the inner side of the substrate. The reflection plate is electrically connected to the conductive film, and faces toward the first point. Provided is an antenna device which is suited to miniaturization and is capable of increasing directivity.
