这项工作提出了使用基于银纳米颗粒的油墨对高达67 GHz的毫米波传输线进行保形印刷。几个共面（CPW）线已经打印在3D氧化铝测试结构上，如斜坡、半球体和山脊，所有这些都是使用陶瓷增材制造技术制造的。在60 GHz范围内，所有实现的传输线回波损耗均小于10 dB，插入损耗均小于0.8 dB。对气溶胶喷射打印（AJP）技术所获得的性能进行了大量的测试。在平面（3D陶瓷对象为24 μm）上获得了最小特征（线宽，线间距）至16.5 μm，同时在49.2 GHz下获得了2.1107S/m的高电导率。
This work presents the conformal printing of milli-meter-wave transmission lines up to 67 GHz using inks based on silver nanoparticles. Several coplanar (CPW) lines have been printed over 3D Alumina test structures such as slope, half-sphere and ridge, all of them being fabricated using a ceramic additive manufacturing technology. All of the achieved transmission lines show a return loss better than 10 dB and insertion loss better than 0.8 dB up to 60 GHz. Extensive tests have been done on the performances obtained with the Aerosol Jet Printing (AJP) technology. Minimum features (line width, lines spacing) down to 16.5 μm have been obtained on flat surfaces (24 μm on 3D ceramic objects) while obtaining a high conductivity of 2.1107S/m at 49.2 GHz for the directly printed silver layers.
