AI summary

An antenna device according to one of various examples of the present invention can comprise: an antenna module; a radio remote head (RRH) for receiving signals from the antenna module and a base station; guide modules for guiding the RRH such that the RRH slidably moves in an inclined state in the antenna module, for providing one end portion of the RRH to be rotated, and for providing the other end portion of the RRH to move vertically in the sliding movement direction; connection modules provided on a surface on which the antenna module and the RRH face each other, and electrically connecting the RRH and the antenna module; and coupling modules provided on one side of the RRH so as to move the connection modules, thereby mutually coupling or separating the connection modules.
