A base station antenna includes a plurality of antenna arrays and a phase dispersion circuit. The plurality of antenna arrays include a plurality of radiating elements, and the plurality of radiating elements include a first radiating element and a second radiating element that have a horizontal spacing. The phase dispersion circuit is configured to adjust a phase slope of an electromagnetic signal of the first radiating element in an operating frequency band and/or a phase slope of an electromagnetic signal of the second radiating element in the operating frequency band.

Base station antenna and base station

Embodiments of this application disclose an antenna. The antenna includes a balun structure, a radiation structure disposed on the balun structure, and a coupling structure disposed on the radiation structure. The coupling structure is configured to eliminate or mitigate an interference current, to reduce impact of the interference current on the antenna, thereby reducing radiation of the antenna on the interference current.

Antenna and communications device

The present disclosure relates to two-dimensional antennas and network devices. One example antenna includes a reflection panel, at least two antenna arrays, at least one common feeding network, and at least two array feeding networks. The at least two antenna arrays are on the reflection panel. Each antenna array comprises at least one independent radiation unit and at least one common radiation unit.

A method for managing uplink carrier frequencies is provided, which is applicable to the field of communication. The method includes the following steps: A state switching response message sent by a UE is received, where the state switching response message includes a result of state switching performed by on a secondary uplink carrier serving cell; The result of the state switching is notified to a secondary uplink carrier non-serving cell in a secondary carrier active set through an RNC. A device and a system for managing uplink carrier frequencies are further provided. Through the method, device, and system provided in embodiments of the present invention, the uplink carrier frequencies are managed, so as to facilitate transmission of uplink data during multi-cell collaboration.
