A novel filter prototype composed of multistage of stepped impedance resonators (SIRs) is proposed to realize the ultra-wideband bandpass (UWB) filter. The relation between the modes number and stage number of resonators is firstly discussed, followed by the derivation of the corresponding Chebyshev filtering function. Furthermore, the equivalent circuit model of this new filter prototype is established...
Substrate integrated waveguide (SIW) technology provides an attractive solution to the integration of planar and nonplanar circuits by using a planar circuit fabrication process. However, it is usually difficult to implement the negative coupling structure required for the design of compact canonical folded elliptic or quasi-elliptic cross-coupled bandpass filter on the basis of a single-layer SIW...
A novel compact ultra-wideband (UWB) bandpass filter is proposed to meet federal communications commission (FCC)'s spectrum mask. Shunt short-circuited stubs and the parallel coupled stepped-impedance resonators (SIRs) are used to achieve a fraction passband from 3.1 GHz to 10.6 GHz. The equivalent circuit of the newly proposed filter is established, while the corresponding chebyshev-type transfer...
A new type of parallel-coupled microstrip filter is proposed to have wide-band performance and suppress the second harmonic response. The proposed filters are constructed with using floating plate overlays to enhance the coupling between microstrip lines, and compensate the difference in phase velocity under even- and odd-mode excitations. The synthesis method is well developed and the design curves...
Substrate Integrated Waveguide (SIW) has been demonstrated for the design of low-cost planar waveguide bandpass filters in the same process as planar circuits. However, SIW cavity resonator generally has a finite Qu of around 500 with most commonly used dielectric substrates, which rounds the passband edge and reduces the effective bandwidth of narrowband filter. In this paper, a K-band bandpass filter...
