摘　　要：本文提出不等波纹函数低通原型,并对其理论进行初步探讨。切比雪夫函数及最平坦型巴特沃兹函数皆为其特例。文中给出不等波纹函数低通原型归一化元件值的一般计算公式与二一四阶的具体公式。还讨论了不等波纹函数的几个性质。最后给出两个应用实例:消除耦合环自感部分的影响;抑制高次模的微带圆盘腔带通滤波器。In this paper the unequiripole function lowpass prototype has been introduced, and the relative theory has been studied initially. The Chebyschev or Butterworth function is the special type of this function. The formulas for calculating the normalized elements giof the unequiripple function lowpass prototype are given and several characters of this function are discussed. Finally two examples of this theory are applied, for eliminating the influence of coupling loops and designing microstrip circular disk cavity filter suppressed higher modes to get wide stopband.
