현재 주목을 받고 있는 테라헤르츠 대역의 주파수를 이용한 무선통신시스템 응용기술 동향에 대하여 기술한다. 테라헤르츠 대역은 전자파 스펙트럼에서 밀리미터파 대역과 원적외선 대역의 중간에 위치하는 100GHz~10THz 사이의 주파수이다. 현재 시점에서 10년 이내에 약 15Gbps의 데이터 속도가 필요할 것으로 판단되며, 10Gbps 이상의 전송속도를 실현하기 위해서는 기존의 밀리미터파에서 사용하는 주파수 대역폭 보다 더 넓은 대역폭이 필요하며, 이 대역폭을 얻기 위해서는 테라헤르츠 주파수 대역으로 자연적으로 옮겨가지 않을 수 없다. 본 고에서는 테라헤르츠 대역의 전파 특성, 가용 주파수 대역과 무선통신시스템 응용을 위한 옥내 채널 모델, 테라헤르츠 무선통신시스템 연구동향, RF 송수신기 핵심부품 및 MMIC 기술개발 동향을 소개하고자 한다.
