本文是关于频率范围高达340 GHz的传输线丝网印刷金属化的传输损耗的第一份报告。我们观察到，与商业化阻抗标准基板（ISS）上的传统线路相比，印刷传输线的传输损耗显著降低。Ag金属化的导电性被认为是这种降低的损失的原因。虽然在制造后约3年在传输线中观察到损耗的退化，但印刷线保持比国际空间站上的常规线更小的损耗。此外，尽管印刷线具有较差的生产再现性，但丝网印刷技术被认为是用于制造毫米波电路的改进的解决方案，即使在300 GHz频带中。
: This paper is the fi rst report on transmission loss of screen-printed metallization of transmission lines at frequencies ranging up to 340 GHz. We observed that the printed transmission lines exhibited signi fi cantly reduced transmission losses when compared to conventional lines on the commercialized impedance standard substrate (ISS). The conductivity of Ag metallization was considered the reason for this reduced loss. Though degradation of the loss was observed in transmission lines approximately 3 years post fabrication, the printed line retains a smaller loss than conventional lines on the ISS. Further, despite the printed line having inferior production reproducibility, the screen-printed technology was considered to be an improved solution for the fabrication of millimeter-wave circuits, even in the 300 GHz band.
