Resumen:


In this paper, a substrate integrated waveguide (SIW) loaded with three pairs of modified complementary


split-ring resonators (CSRRs) is presented, in which the subwavelength waveguide passband can be significantly


increased due to the appearance of new electromagnetic couplings between the different resonators. The obtained


results are compared to those provided by a more classical topology based on CSRRs periodically etched along the


waveguide wall, showing a significant bandwidthimprovement, while maintaining a good matching level.
