| 摘 要： | 用均匀带电圆筒模拟带电弹壳分析了弹壳静电分布对微带天线谐振频率、方向图和增益的影响.首先,采用拉普拉斯方程法推导了均匀带电圆筒空间远场计算公式.然后,运用唯一性定理和场的迭加原理得到了合成场远场计算公式.最后,根据理论分析所得到的结果利用Matlab计算了微带天线辐射方向图,并分析了微带天线辐射方向图随着圆筒不同带电量的变化情况.

| Abstract: | The effect of electrostatic field distribution of cartridge on resonant frequency, pattern and gain of microstrip antennas is analyzed with uniformly charged cylinder simulating charged cartridge. Firstly, the spatial far field formula of uniformly charged cylinder is deduced by using the method of Laplaces equation. Secondly, the composite far field formula is obtained by using the uniqueness theorem and the superposition principle of field. Finally, the radiation pattern of the microstrip antennas is calculated by Matlab according to the result of theoretical analysis, and the radiation pattern's variation of microstrip antennas with different charges of cylinder is analyzed. |
