each feed port 110 of the antenna 11 is connected with a corresponding radio frequency module 12.
The rf modules 12 may be in one-to-one correspondence with the feed ports 110 of the antenna 11. It should be noted that, in practical applications, the number of the feeding ports 110 may be greater than the number of the rf modules 12, so as to facilitate the outflow of the spare feeding ports 110, and when the rf modules 12 need to be added, the feeding ports 110 may be directly connected to the spare feeding ports.
