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.

Abstract: An array antenna and a network device are provided. The array antenna includes n radiating elements, a power splitter or a phase shifter, and a switching switch. The power splitter or the phase shifter includes n output ends and m input ends. The switching switch includes m first ports, K second ports, and a switch element, where the m first ports are respectively connected to the m input ends; and the K second ports are configured to couple an input signal. The switch element is configured to switch a connection relationship between the m first ports and the K second ports, so as to selectively output the input signal to at least one first port.

Abstract: The present application provides a multi-frequency array antenna. The multi-frequency array antenna includes at least one dual-polarized low frequency subarray (21) and at least one dual-polarized high frequency subarray (22), where the dual-polarized low frequency subarray (21) and the dual-polarized high frequency subarray (22) are arranged, within a same radome (23), in parallel along an axial direction (24) of the multi-frequency array antenna, the dual-polarized low frequency subarray includes at least two types of dual-polarized low frequency radiation unit pairs (211), and each of the dual-polarized low frequency radiation unit pairs includes at least four low frequency radiation units. In this structure, effective working regions of the multiple low frequency radiation units in each dual-polarized low frequency radiation unit pair cover a larger area, and therefore diameter utilization of the dual-polarized low frequency radiation unit pair is higher, and a gain of the low frequency subarray is higher.
