Abstract：In order to improve the performance of the filter,a new type of guided waveguide integrated waveguide is studied, through study the transmission mode of square SIW resonator. The upper sideband and the lower sideband of the bandpass filter are separately suppressed by two rectangular resonators,and are connected through the microstrip line to obtain a highly selective K-band SIW bandpass filter. The simulation is performed by HFSS software,and the simulation result is consistent with expecta?tions. The filter has a center frequency of 16GHz,a bandwidth of 0.9GHz,and a relative bandwidth of 5.6%.
