Abstract :
This work presents a novel class of filters in substrate integrated waveguide (SIW) technology, based on a multilayered configuration. The peculiarity of these filters is the presence of additional poles and zeros, due to the resonant slot etched in the common metal layer between two dielectric substrates. In this way, a filter with two mono-modal cavities, coupled by a resonant slot, exhibits a frequency response with three poles and two transmission zeros. The experimental verification of a prototype operating at 11 GHz is presented in this letter, and the possible extensions of this filter topology are discussed.
