Abstract :
In this article, a novel dual mode dual band substrate integrated waveguide (SIW) filter is presented. Dual band operation of the filter is realized by providing two paths for the input signal to the output port. The signals of two paths have opposite sign and equal amplitude at a frequency between two bands and hence, a transmission zero is generated in this frequency. The dual mode resonator is a square SIW cavity perturbed by corner cut. A three-cavity dual mode dual band filter is designed using coupling matrix. Frequency response of the filter obtained from the coupling matrix is in good agreement with the full wave simulation result.
