射频 天线中的 寄生
原话是
The loaded elements are parasitic to the driven patch,but are shorted to the ground plane
这里面的parasitic 寄生 怎么理解

天线设计中的"寄生"与射频电路设计中的"寄生"参量应属相同的意思.
在天线实际的模型中,往往会因天线结构、材料特性和表面边界条件的非理想因素对天线总体性能产生附加影响.这些附加影响的参数化,即被称为寄生参量.
例如:在天线等效路模型中,寄生参量通常被等效为串联或并联接入的电容和电感;在场模型中,寄生参量则可被视为,除主模之外被激励或共存的高次模.
