摘要：
将铁电材料特别是锶钡钛酸盐(BaxSr1-xTiO3)这类强非线性介质的压电非线性特性[1]应用到微带贴片天线的介质基片上,通过改变基片的等效介电系数e来实现微带天线的可调谐工作,对此方法进行了可行性研究,给出了理论验证性质的简单设计和仿真结果。

Abstract: This paper presented a new type tunable antenna which was designed with ferroelectric film materials.Because of the nonlinear dielectric property of the ferroelectric film,the authors could change the resonance frequency of the microstrip antenna by change the relative permittivity of the substrate.Finally gave design examples and used electromagnetic field simulation software to have modeling and simulating works done.
