The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting higher data transmission rates than a 4th generation (4G) communication system such as long-term evolution (LTE). An antenna module in a wireless communication system includes: a printed circuit board (PCB); a radio frequency integrated circuit (RFIC); and a plurality of antenna elements for emitting a radio frequency (RF) signal, wherein the plurality of antenna elements may be disposed in a first area of a first surface of the PCB, and the RFIC may be disposed in a second area, different from the first area, of the first surface of the PCB.
