The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. An antenna module includes a first printed circuit board (PCB) stacked at least one layer, and a second PCB disposed on an upper surface of the first PCB and stacked at least one layer. The antenna module further includes a wireless communication chip disposed on an upper surface of the second PCB and controlling an electrical signal for a radio frequency, a first structure disposed on the upper surface of the first PCB and surrounding the upper surface of the first PCB, a first antenna disposed on an inner surface of the first structure to face the first PCB, and a feed line electrically connecting the first antenna and the wireless communication chip.
