摘要：
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 pass-band. 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. (C) 2004 Wiley Periodicals, Inc.
