Apparatus and method for controlling antenna in mobile communication system

The present invention relates to an apparatus and a method for controlling an antenna in a mobile communication system. The present invention includes installing a remote electric tilt (RET) antenna by a daisy chain separately from a daisy chain structure of a radio frequency unit (RU), thereby, a cable used for individually connecting the RU to the RET antenna can be reduced in length so as to reduce a consumption of materials, and the RET antenna can be installed without an installation of a power amplifier.
