Novel multi-band filter design and Substrate Integrated Waveguide filter realization

A novel compact dual-band bandpass waveguide filter is presented in this paper. H-plane metal inserts with complementary split-ring resonators are implemented as resonating elements in the standard (WR-90) rectangular waveguide. Design starts from the models of the waveguide resonators with two resonant frequencies (9[Formula: see text]GHz and 11[Formula: see text]GHz) using a single flat or folded metal insert. Further, folded inserts are used for the second-order dual-band filter design. The equivalent circuits are proposed for the considered waveguide resonators and filter. A good agreement of the amplitude responses obtained for three-dimensional electromagnetic models and microwave circuits is achieved. Finally, compact dual-band bandpass waveguide filter is proposed as a novel solution using miniaturized inverters for both central frequencies. Compact filter model is further modified in order to obtain solution customized for easier fabrication. For the compact filter model, amplitude response is experimentally verified. The required filter response is preserved, as verified by a good agreement of the results obtained for the original dual-band filter and for the compact filter solutions.

In this study, we presented an integrated approach to the design of digital filters using the digital filter package (DFP). We added four new features to DFP: multi-band filter design, adaptive filter design, two-dimensional filter design and TMS320 code generation. We discuss each of these new features from design consideration to realization. We present design examples and demonstrate the design results generated by DFP. We also discuss GUI design in MATLAB, the DFP GUI design structure and the data transition structure from one DFP function to another. We show that DFP can allow efficient design of the flollowing filter structures: low pass filter, high pass filter, band pass filter, band stop filter, multi band filter, differentiator, Hilbert Transformer, adaptive and 2D filters. DFP allows the use of a variety of FIR and IIR design methods as well as hardware implementation structures; it provides a useful tool to quickly examine a variety of filters and understand the trade-offs involved in varying the characteristics of the filter.
