采用喷墨印刷技术在玻璃基板上制造传输线。在康宁7740玻璃基板上使用10 pL滴体积实现了50微米的分辨率。采用本文所述的其他方法可以进一步改善这一点。在远低于体银熔点的温度下烧结后，银结构的电导率仅为体银的1/6。对烧结银的直流电阻进行了比较，表明它可以与电镀铜和蚀刻铜相匹配。打印的共面线在10 GHZ和20 GHZ下的损耗分别为1.62 dB/cm和2.65 dB/cm。
Inkjet printing technology was utilized to fabricate transmission lines on a glass substrate. 50 micron resolution was realized using 10 pL drop volumes on a Corning 7740 glass substrate. This can be further improved by applying other methods as described in this paper. The conductivity of the sintered silver structures were 1/6 that of bulk silver after sintering at a temperature much lower than the melting point of bulk silver. A comparison of the DC resistance of the sintered silver shows that it can be a match for electroplated and etched copper. Printed Coplanar lines demonstrated losses of 1.62 dB/cm at 10 GHZ and 2.65 dB/cm at 20 GHz.
