Remote electrical tilt antenna, base station, and method for aligning RCU and RF port

摘要

A remote electrical tilt antenna with a mismatching device built in and a method for matching a remote control unit with a radio frequency port are provided, which can accurately and efficiently determine a matching relationship between an RCU and an RF port. The remote electrical tilt antenna includes: an RCU, configured to receive a drive instruction, and further configured to drive the gear; the gear, where the gear is connected to a phase shifter, the gear is driven by the RCU, and the gear, driven by the RCU, is configured to drive the phase shifter; and the phase shifter, where the phase shifter is configured to adjust a direction of an antenna beam, and a mismatching device is built in the phase shifter, where the mismatching device is associated with a radio frequency RF channel, and the mismatching device is configured to enable the RF channel to generate impedance mismatch.
