不等波纹函数的综合与分析方法及其在微波领域中的应用

The Synthesis and Analysis Procedure of Unequiripple Function And Its Application in the Microwave Area

将低通原型网络的特征函数扩展为奇次或偶次多项式,将其命名为不等波纹函数。文中讨论了不等波纹函数型低通原型网络的特征,导出综合与分析方法的公式。给出两个应用实例:(综合)设计收、发共用(通信)天线元的带阻式阻抗匹配网络;设计Ku/Ka频段的低通型MEMS移相器。这两个实例均为用不等波纹函数综合与分析方法得到的新型微波器件。

In this paper the characteristic function of the lowpass prototype network is spreaded out the even or odd polynomial, and this polynomial is named after the unequiripple function. The characters for the type unequiripple function lowpass prototype network is investigated, and the formulas of the synthesis and analysis procedure are obtained. Two application examples are given： the synthesis procedure of stopband type impedance matching network in the antenna with reception and transmission; designing the lowpass type MEMS phase shifter on Ku/Ka band. These examples are the new microwave devices.
