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: Embodiments of the present invention pertain to the field of communications technologies and disclose a multi-band antenna and a communications device. The multi-band antenna includes a reflection panel, at least one high-frequency unit, and at least one low-frequency unit. Each high-frequency unit includes a balun structure, a coupling structure, and a radiation arm structure. The balun structure includes two balun sub-structures, the coupling structure includes two coupling sub-structures, and the radiation arm structure includes two radiation arms. The high-frequency unit and the low-frequency unit are disposed on the reflection panel. Each coupling sub-structure is separately electrically connected to one balun sub-structure and one radiation arm. The coupling sub-structure is configured to transmit a signal whose frequency is higher than a preset threshold, and block a signal whose frequency is lower than the preset threshold.
