The impacts of printing process and curing condition on antenna resistance are shown as follows: higher resistance of a printing antenna is generated not only by higher print pressure and velocity, which result in inadequate ink transfer, but also by lower curing temperature and shorter curing time, which can result in imperfect combustion of organic vehicles in silver ink.

印刷工艺与固化条件对天线电阻的影响主要表现在：较高的印刷速度与印刷压力会使银浆转移不充分，并导致天线电阻增加；而较低的固化温度、较短的固化时间也会使银浆中的有机载体不能充分燃烧，从而增加天线电阻。

The relationship between the screen mesh and the theoretical and practical ink film thickness was analyzed based on the main influencing factors of the ink film thickness by screen printing. A calculation model for the ink thickness was established based on the screen under static and compressive deformation.
