New Bandstop Filter Using Simple Defected Microstrip Structure

A defected microstrip structure (DMS) has similar properties as a defected ground structure (DGS), but without any leakage through the ground plane. In this article, the stopband performance of a DMS is studied, and new single-band and dual-band bandst...
Currently, the defected ground structure (DGS) 1-4 has been widely employed to improve filter performance and reduce filter size. DGSs show good stopband performance and excellent harmonic suppression in microwave circuits design and especially the periodic DGSs, 4 which extend the stopband greatly. DGS increases the effective capacitance and...

Determination of Transmission Zeros of Self-Equalized Cross-Coupled Resonator Bandpass Filters

A method to determine the filter order and the locations of transmission zeros of self-equalized bandpass filters is presented, according to given filter specifications by optimization. The objective error function for the optimization is computed from...
In many RF/microwave communications systems, a bandpass filter with a flat group delay is demanded, in addition to its selectivity. One way to obtain this is by designing a self-equalized filter, in which the group delay equalizer is realized within the filter itself. In general, for a self-equalized filter,...
