研究了一种在聚对苯二甲酸乙二醇酯(PET)基板上喷墨打印的毫米波天线。用DMP-2800系列喷墨打印系统打印了60 GHz共面波导馈电单极子天线。采用纳米银胶体溶液作为印刷油墨。首先，这一过程使用等离子体聚合技术来改善PET表面或印刷。然后，在PET基板上喷墨打印银线，然后在烘箱中固化，以去除多余的溶剂和材料杂质。为了研究表面粗糙度和线宽的变化，打印了多道次的线条。该导电油墨的银膜电导率约为4×10~6 S/m，回波损耗小于-10分贝的印刷天线的测量阻抗带宽为60~65 GHz。
This study investigates an inkjet-printed millimetre-wave antenna on Polyethylene Terephthalate (PET) substrate. The 60 GHz CPW-fed monopole antenna was printed with a DMP-2800 series inkjet printing system. A silver nanoparticle colloidal solution was used as the printing ink. First, this process uses a plasma polymerization technique to improve the PET surface or printing. Then, silver lines are inkjet printed on the PET substrate, followed by curing in an oven to remove excess solvent and material impurities. The multiple-pass lines are printed to study the changes in surface roughness and line width. The silver film conductivity of the conductive ink is around 4×106 S/m. The measured impedance bandwidth of the printed antenna, defined by return loss less than -10 dB, is from 60 to 65 GHz.
