Abstract: An antenna having high isolation and a low cross-polarization level, a base station, and a terminal are provided. The antenna includes a radiation layer, a feed layer, and an aperture coupling layer disposed between the radiation layer and the feed layer. The aperture coupling layer includes a metal sheet. A first feeding slot, a second feeding slot, and a middle slot are configured in the metal sheet. The middle slot is located between the first feeding slot and the second feeding slot, and is located in a weak electric field region of the metal sheet. The middle slot is configured between the first feeding slot and the second feeding slot of the metal sheet.
