n.抑止频带(阻带；不透明带)

There is always a smooth transition between passband and stopband. 通频带和抑止频带之间总是存在一个“平滑切换点”。

Equation for stopband transmission zeros of such lowpass filter is derived from a new equivalent circuit model. 本文基于新的等效电路模型，推导出了此类低通滤波器的阻带传输零点位置。

The proposed period Defected Ground Structure (DGS) provides the excellent cutoff and stopband characteristics. 设计的周期DGS单元结构有非常好的截止和带阻特性。

Factors affecting the stopband characteristic and applications of the structure are also studied. 并研究了影响阻带特性的因素及这种结构的应用。

It is used in the microwave integrated circuits to achieve size reduction and rejection of ripples in stopband. 用在微波集成电路中，可以减小电路尺寸和抑制阻带内波纹。
