| 摘要 |
An antenna device includes: a ground plate; a first patch, provided on one surface side of the ground plate and including two first power feeding portions provided in a region surrounded by a first contour at positions spaced away from a first position with a first distance, configured to resonate with a first frequency; a second patch, provided between the ground plate and the first patch and including two second power feeding portions provided in a region surrounded by a second contour at positions spaced away from a second position with a second distance and a slit formed in the region, configured to resonate with a second frequency lower than the first frequency; and an inter-patch connection portion configured to electrically couple the first position of the first patch and the second position of the second patch. |
