5th-세대 이동통신은 기지국뿐만 아니라 이동 단말기에도 다중소자 배열 안테나를 사용한다. 다중 소자 배열 안테나를 효율적으로 설계하기 위해서는 DOA(도착 방향)와 DOD(방향 이탈 방향)의 특성을 획득하는 것이 중요하며, 매우 정확하고 간단한 측정 방법이 필요합니다. 본 논문에서는 Rx와 Tx 측 모두에 처리된 합성 조리개(SA)를 적용하여 DOA와 DOD를 매우 정확하고 간단하게 측정하는 방법을 제안합니다. 또한 제안된 방법에 빔 스캐닝을 추가하면 피크 검출 분해능을 유지하면서 측정 시간을 줄일 수 있음을 보여줍니다. 또한, 실제 전파원을 이용한 무향실과 차폐실에서의 실험을 통해 DOA와 DOD를 높은 정확도로 검출할 수 있음을 확인했습니다.

Abstract: The 5th-generation mobile communication uses multi-element array antennas in not only base stations but also mobile terminals. In order to design multi-element array antennas efficiently, it is important to acquire the characteristics of the direction of arrival (DOA) and direction of departure (DOD), and a highly accurate and simple measurement method is required. This paper proposes a highly accurate and simple method to measure DOA and DOD by applying synthetic aperture (SA) processed at both Rx and Tx sides. It is also shown that the addition of beam scanning to the proposed method can reduce the measurement time while maintaining the peak detection resolution. Moreover, experiments in an anechoic chamber and a shielded room using actual wave sources confirm that DOA and DOD can be detected with high accuracy.

AB - The 5th-generation mobile communication uses multi-element array antennas in not only base stations but also mobile terminals. In order to design multi-element array antennas efficiently, it is important to acquire the characteristics of the direction of arrival (DOA) and direction of departure (DOD), and a highly accurate and simple measurement method is required. This paper proposes a highly accurate and simple method to measure DOA and DOD by applying synthetic aperture (SA) processed at both Rx and Tx sides. It is also shown that the addition of beam scanning to the proposed method can reduce the measurement time while maintaining the peak detection resolution.
