Abstract
In this manuscript, a dualband bandpass filter is designed and fabricated in X and K frequency bands. The proposed filter is implemented based on the half mode substrate integrated waveguide technology. Two resonant slots and a complementary split ring resonator are etched on the top metallic layer of the proposed structure. Therefore, the proposed filter can be easily integrated to other lateral components. Moreover, an efficient method is presented to extract the equivalent circuit model of the dual band filter. The proposed model is investigated in four separate stages to considerably reduce the encountered complexity. A theoretical background is utilized to provide the primary values of the circuit elements. These circuit elements are further modified using an optimization algorithm to provide best matching with full wave simulations. Finally, the designed filter is fabricated to validate the simulation and equivalent circuit results. The operational frequencies and fractional bandwidths of the dual band filter are 9.9 GHz/48 % and 20.75 GHz/20 %, respectively. The simulation, measurements, and equivalent circuit results are in good agreement together.
