deviation of the antenna radiation resistance seems larger in some textbooks about the electromagnetic theory for the editors have made some similar treatment when discussing the radiation power of short antenna.combining the concept of physical with mathematical tools and the precise results are gained,that is the real radiation resistance of electric dipole antenna is about ten times smaller than that of the approximate results in the actual literature by researching the electromagnetic field theory and average energy density.this offers evidence to grasp the radiated ability accurately.

小 摘要：在部分有关电磁场理论的教材中，编者讨论短天线的辐射功率时，由于作了某些近似处理而所得天线的辐射电阻值偏差较大。从天线辐射的电磁场理论和平均能流密度出发，使物理概念和数学工具相结合，运用矢量运算推导出精确的结果，即电偶极子天线的实际辐射电阻要比文献中的近似结果小数十倍，因而为准确把握天线的辐射能力提供了依据。

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. The relation curve between the screen mesh and the ink film thickness was fitted and the suitable printing craft parameter was chosen to print two kinds of RFID tag antennas. The fluctuation of the antenna resistance was analyzed to demonstrate the reliability of the passive RFID tag antenna manufactured by screen printing technology.
