本文重点研究了基于实际参数的典型喷墨印刷折叠偶极子天线的工艺依赖性。我们提出的影响，宽度的变化和数量上的天线性能，如增益，辐射效率和输入阻抗的叠印次数。此外，我们调查的读取范围退化的标签上的天线连接，由于宽度或厚度的变化。此外，还对普通纸质基板上的喷墨印刷天线和印刷电路板（PCB）上的铜天线进行了比较，显示了印刷银天线作为一种低成本解决方案的强大竞争力。
This paper focuses on the process dependence of an inkjet printed folded dipole antenna based on practical parameters in a typical inkjet printing process. We present the effect of width variations and number of overprinting times on the antenna properties such as gain, radiation efficiency and input impedance. Furthermore we investigate the read range degradation of the tag on which the antenna is attached, due to width or thickness variations. In addition, an comparison between an inkjet printed antenna on a regular paper substrate and a copper antenna on Printed Circuit Board (PCB) was made, manifesting the strong competitiveness of the printed silver antenna as a low cost solution.
