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: A multicast service processing method and an access device. In the method, an access device receives an on-demand request; the access device separately sends the on-demand request to a multicast source device through a first uplink port of the access device and a second uplink port of the access device, so that the multicast source device sends a first multicast packet and a second multicast packet based on the on-demand request; the access device receives the first multicast packet through the first uplink port of the access device, and receives the second multicast packet through the second uplink port of the access device; the access device obtains a multicast data stream based on attribute information of the first multicast packet and attribute information of the second multicast packet; and the access device sends the obtained multicast data stream to the program terminal.

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.
