Abstract

This paper presents a new compact and simple microstrip‐patch bandpass filter structure using only one resonator. This filter has two transmission zeros on the both sides of the passband. The volume of this filter is about 1/3 or 1/2 of a conventional filter. Because the new filter is without coupling gaps, uncertainty during fabrication can be reduced. The effects of varying the parameters of the structure have been studied. The simulated results agree well with the measured results. © 2004 Wiley Periodicals, Inc.

A novel microstrip transversal bandpass filter is proposed by replacing the full-wavelength resonator with two shorter resonators; in order to achieve simultaneous spurious response suppression and dual zero implementation. These two zeros can be easily tuned by the above resonators. A prototype fil
