【摘要】 GPS接收天线,反射面馈源等天线的设计需要对于天线的相位特征加以考虑。仿真软件在相位方向图的计算上可能存在一定误差,继而影响到对于相位特征有较高要求的天线设计。本篇文章通过比较对于同一模型在不同仿真仿真软件下与不同求解设臵下的计算结果,说明仿真软件在天线相位方向图上的误差,并主要分析该误差在CST微波工作室下产生的原因。更多还原

【Abstract】 Antenna phase characteristics are needed to be considered in the design of such types of antenna as the GPS receiving antenna or the feed of the reflector. Errors in the results calculated by the simulation software might affect the antenna design with relatively high standard on antenna phase characteristics. This paper compares the antenna phase pattern obtained from theory and simulation software and tries to reason the errors in the phase pattern calculation of the CST microwave studio.更多还原
