우리는 오프셋 계단식 포스트로 구성된 T-접합 OMT를 제안합니다. 오프셋된 계단형 포스트는 반대편 측벽에 위치한 단락 회로에서 두 개의 직사각형 포트를 일치시키는 데 기여합니다. 기존의 능선이 없는 구조는 단순하며 견고한 성능을 구현합니다. 우리는 상업용 금속 3D 프린터를 사용하여 단일 알루미늄 합금 조각으로 제안된 T-접합 OMT를 제작했습니다. 제작 공차 및 표면 거칠기와 같은 3D 프린터의 단점을 극복하기 위해 견고한 성능을 갖춘 간단하고 컴팩트한 구조가 제안되었습니다. 측정 결과, K-밴드 대역폭 22%에서 반사 손실 0.3dB, 삽입 손실 8dB을 나타냈습니다.

Abstract: We propose a T-junction OMT consisting of an offset stepped post. The offset stepped post contributes to the matching of two rectangular ports at the short circuit, situated at the opposite side walls. The structure without conventional ridges is simple and makes it possible to achieve robust performance. We fabricated a proposed T-junction OMT in a single piece of an aluminum alloy, using a commercial metal 3D-printer. The simple and compact structure with robust performance is proposed to overcome the disadvantages of a 3D-printer, such as fabrication tolerance and surface roughness. The measured results demonstrated a return loss of 22dB and an insertion loss of 0.3dB, with a bandwidth of 8% in the K-band.
