Abstract: An antenna includes a radiating element, a reflective baseplate, a metal enclosure frame, a first reflective surface, and a radiation cavity. The radiating element is on the reflective baseplate and is below the first reflective surface. The reflective baseplate is rectangular. A length of the reflective baseplate is greater than a width of the reflective baseplate. The metal enclosure frame is connected to and encircles the reflective baseplate. The metal enclosure frame includes four enclosure frame surfaces. The four enclosure frame surfaces include two first enclosure frame surfaces, and two second enclosure frame surfaces. The first enclosure frame surfaces are electrically connected to first sides of the reflective baseplate. The second enclosure frame surfaces are electrically connected to second sides of the reflective baseplate. The first sides are greater than the second sides. The first reflective surface includes a secondary reflective surface or a partially reflective surface.

Abstract: This application provides example antennas and example base stations. One example antenna includes a reflection panel, a radiating element, and a resonator group. The resonator group is disposed between the reflection panel and the radiating element. The resonator group includes a first resonator, a second resonator, and a third resonator. The third resonator has a first connection portion and a second connection portion that are located at at least one open-circuit end. The first resonator is coupled to the first connection portion. The second resonator is coupled to the second connection portion. The third resonator is further coupled to the radiating element, and a signal may be transmitted between the third resonator and the radiating element. The first resonator is configured to transmit a signal in a first frequency band. The second resonator is configured to transmit a signal in a second frequency band.
