In this work, the behavior of a Complementary Split Ring Resonator (CSRR) operating within the
quasi-static resonance regime and embedded in a composite stratified Substrate Integrated
Waveguide (SIW) with two different dielectric layers is analyzed. In these conditions, the propagating
modes within the SIW combined with the imposed non-symmetrical structure lead to the excitation
of the CSRR elements inside the SIW at difference with conventional excitation. Several cases
of CSRR loaded SIW are proposed, and their electromagnetic field components as well as their frequency
response are analyzed, providing insight into the CSRR resonance excitation. A test prototype
has been designed, fabricated, and measured, showing a good agreement with simulation results
and providing a new alternative for the implementation of compact frequency selective devices compatible
with planar technology and without undesired radiation loss.
