The present invention relates to a communication technique for fusing a 5G communication system to support a higher data transmission rate than a 4G system, with IoT technology, and a system thereof. This disclosure is based on 5G communication technology and the IoT related technology and can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security, safety-related services, or the like). In addition, the present invention provides an antenna module comprising an antenna and a lens, wherein the antenna comprises a first antenna array which deflects and radiates a radio wave from a vertical plane of the antenna by a predetermined first angle, and the lens can be spaced apart from the antenna by a first determined distance to change the phase of the radio wave radiated from the antenna.
