Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/002162
Kind Code:
A1
Abstract:
An antenna device (100) is provided with: a rectangular conductor pattern (20) that is disposed substantially parallel to a ground plane (10) at a predetermined interval; a short-circuiting section (30) that is electrically connected to the conductor pattern (20) and the ground plane (10); a first feeding point (40) for transmitting/receiving first frequency signals; and a second feeding point (50) for transmitting/receiving second frequency signals. The electrical length of one side of the conductor pattern (20) is half the wavelength of the second frequency. The short-circuiting section (30) is provided at a center part of the conductor pattern (20), and the area of the conductor pattern (20) is the area with which capacitance that resonates in parallel at the first frequency with inductance provided in the short-circuiting section (30) is formed.
