Techniques related to a 5th generation (5G) or pre-5G communication system to support higher data rates after a 4th generation (4G) communication system such as long term evolution (LTE) ae provided. A reflector is provided that is configured to change a direction of a beam incident in a first direction to a second direction different from the first direction, so that a receiving entity positioned in a shadow area caused by an object can receive the beam. Therefore, the reflector removes the shadow area at which the beam does not arrive in a 5G wireless communication system.
