In this paper, a dual-mode dual-band bandpass filter with controllable in-between isolation is presented using a single microstrip ring resonator. By installing two dispersion-controlled coupled-line sections on the ring resonator at the two ports with 90°-separation, two transmission poles can be easily emerged and distributed in each passband. Meanwhile, two transmission zeros are generated between...
In this paper, synthesis design of a class of ultra-wideband parallel-coupled line bandpass filters with Chebyshev responses is presented. Through the exact synthesis approach with virtue to closed-form insertion loss function, characteristic impedances of each coupled and connecting line section are explicitly determined. Based on the obtained impedance values, the realizable range of filtering bandwidth...
A class of ultra-wideband microstrip-line bandpass filters with improved out-of-band performance and miniaturized size is proposed and constituted using electromagnetic-bandgap (EBG) embedded multiple-mode resonator (MMR). This EBG- embedded MMR is at first studied, aiming to relocate its first three resonant modes within the 3.1-10.6GHz UWB passband while inhibiting its 5th resonant mode in the upper...
