Abstract

A radiation element includes: two or more radiation arms; two or more power feeders for respectively feeding the two or more radiation arms; and a filter, configured between the two or more radiation arms and the two or more power feeders. An antenna includes a first radiation unit that includes the radiation element, a second radiation unit that includes a high-frequency radiating element, and a reflection plate. The first radiation unit and the second radiation unit are configured on the reflection plate. In a direction perpendicular to the reflection plate, the radiation element and the high-frequency radiating element at least partially overlap.
