Document Type and Number:
WIPO Patent Application WO/2017/002159
Kind Code:
A1
Abstract:
This antenna device is provided with: a substrate; a first linear conductor element, which is disposed on the substrate such that the first linear conductor element has a loop shape that is line-symmetric to a first straight line and a second straight line orthogonal to the first straight line, and in which the electrical length between points intersecting the second straight line is the integral multiple of the wavelength at a resonant frequency; and a second linear conductor element, which is disposed on the substrate, and is substantially parallel to the second straight line, and in which the electrical length is a half the wavelength at the resonant frequency.
