Harmonic pass-band suppression in coupled-serial-shunted lines Elliptic band-pass filters

摘要

A synthesizing method is presented to design Elliptic band-pass filters in the microwave frequency range. The Elliptic band-pass filter is implemented by using a coupled-serial-shunted line structure. Using a continuous perturbation of wiggly-groove and ring resonator of the couple line the harmonic pass-band of the filter is rejected. An Elliptic band-pass filter is implemented to validate this method correct by measuring.
