An antenna element is provided with an upper conductor, lower conductors, leg portions and feeding portions. The upper conductor is formed with aperture portions. The upper conductor has a middle portion, a ring portion and coupling portions. The ring portion is located apart from the middle portion and continuously surrounds the middle portion. The aperture portions are located between the middle portion and the ring portion in plan view. Each of the coupling portions couples the middle portion onto the ring portion. The leg portions extend from the ring portion. The lower conductors are apart from the upper conductor in an up-down direction and connected to the leg portions. the feeding portions extend from the upper conductor.

Antenna element and antenna device

An antenna element comprises an upper conductor, first lower conductors, second lower conductors, first leg portions, second leg portions and feeding portions. The upper conductor has a middle portion, a ring portion and coupling portions. The ring portion continuously surrounds the middle portion, and the coupling portions couple the middle portion and the ring portion to each other. The first leg portions extend from the middle portion, and the second leg portions extend from the ring portion. The first lower conductors and the second lower conductors are distinct and separated from one another and are apart from the upper conductor in an up-down direction. The first lower conductors are connected to the first leg portions, and the second lower conductors are connected to the second leg portions. The feeding portions extend from the upper conductor.
