Document Type and Number:
WIPO Patent Application WO/2019/198666
Kind Code:
A1
Abstract:
Provided is an antenna device with a simple configuration, said antenna device supporting a plurality of frequency bands. An antenna device according to the present invention is provided with: at least one first radiation element that is provided on one surface of a substrate and that has a resonant frequency in a first frequency band; at least one second radiation element provided on the one surface of the substrate; a connection line for connecting the first radiation element and the second radiation element on the one surface of the substrate; a conductor that is provided at a position facing the first radiation element in the interior of the substrate and that has a slot; and a power supply line for supplying power to the first radiation element via the slot. The connection line is connected to the center portion, of the first radiation element, in a direction along the direction of polarization of radio waves radiated due to resonance. The line length formed of the first radiation element, the connection line, and the second radiation element is set to a length so as to have a resonant frequency in a second frequency band lower than the first frequency band.
