在本文中，气溶胶喷射印刷技术进行评估D波段射频应用的第一次。介绍了采用银纳米粒子气溶胶喷射印刷工艺在液晶聚合物（LCP）上制作D波段共面波导（CPW）线和CPW到微带线的转换的工艺、技术评估和表征。成功地实现了10 μm分辨率的特征尺寸，这是所有数字印刷技术中最精细的分辨率。在高达200 °C的温度下烧结后，烧结银结构的导电性为本体银的导电性的一半。印刷传输线在110 GHz下表现出0.35 dB/mm的损耗，在170 GHz下表现出0.51 dB/mm的损耗，这比喷墨印刷线的插入损耗小一个数量级。
In this paper, aerosol jet printing technology is assessed for D-band RF applications for the first time. It describes the fabrication process, the technology assessment and the characterization of coplanar waveguides (CPW) lines and CPW to microstrip transitions on liquid crystal polymer (LCP) in the D band using silver nanoparticle aerosol jet printing process. Feature sizes with a resolution of 10 μm, which is the finest resolution among all of the digital printing technologies, were realized successfully. The conductivity of the sintered silver structures was half to that of bulk silver after sintering at temperatures up to 200 °C. Printed transmission lines demonstrated losses of 0.35 dB/mm at 110 GHz and 0.51 dB/mm at 170 GHz that are less than that of the insertion loss of the inkjet printing lines by an order of magnitude.
