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

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.
