Abstract
A communications apparatus includes a phase correction unit, a first radio frequency channel, a first analog bridge, a second radio frequency channel, and a second analog bridge. A first signal is sent to a first input end using the first radio frequency channel, and is divided into at least two channels of first sub-signals by using the first analog bridge. The at least two channels of first sub-signals are respective output from at least two first output ends to at least two first antenna arrays. Similarly, a second signal is divided into at least two channels of second sub-signals by using the second analog bridge, and the at least two channels of second sub-signals are output to at least two second antenna arrays. A first channel of first sub-signal and a first channel of second sub-signal are coupled to the phase correction unit by using a coupler.
