Propomos uma OMT de junção em T que consiste em um poste escalonado deslocado. O poste escalonado deslocado contribui para a correspondência de duas portas retangulares no curto-circuito, situadas nas paredes laterais opostas. A estrutura sem cumeeiras convencionais é simples e permite um desempenho robusto. Fabricamos uma OMT de junção em T proposta em uma única peça de liga de alumínio, usando uma impressora 3D de metal comercial. A estrutura simples e compacta com desempenho robusto é proposta para superar as desvantagens de uma impressora 3D, como tolerância de fabricação e rugosidade superficial. Os resultados medidos demonstraram uma perda de retorno de 22dB e uma perda de inserção de 0.3dB, com largura de banda de 8% na banda K.

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.
