Document Type and Number:
WIPO Patent Application WO/2020/027058
Kind Code:
A1
Abstract:
An antenna device (120) according to the present invention is provided with a ground electrode (GND), a power feed element (121) and a parasitic element (122). The ground electrode (GND) has a generally oblong rectangular planar shape which has first sides extending in a first direction and second sides extending in a second direction that is perpendicular to the first direction. The power feed element (121) has a generally rectangular planar shape, and is formed so that each side thereof is parallel to the first direction or the second direction. The parasitic element (122) is formed so as to face a side of the power feed element (121), said side being parallel to the first sides. The power feed element (121) is configured so as to irradiate a first polarized wave that is excited in the first direction and a second polarized wave that is excited in the second direction. The length of the first sides is longer than the length of the second sides.
