The authors propose a new metamaterial-inspired substrate integrated waveguide (SIW) that utilises broadside-coupled complementary split ring resonators (BC-CSRRs) instead of metalised via holes, to confine propagation within the guiding channel. Due to the resonant behaviour of the BC-CSRRs, blocking of in-plane propagation is achieved in a straightforward and efficient manner. The final waveguide is synthesised by employing two rows of CSRRs instead of each via row, resulting in a fully-planar, easy to fabricate, cost-effective solution. This new waveguide exhibits outstanding propagation characteristics, with losses close to those of the conventional SIW, providing a highly promising platform to implement low-cost planar components for millimetre-wave applications. To further confirm the potential of implementing CSRR-based SIW components, they provide designs of leaky-wave antennas in the X- and Ka-band, utilising this new concept.

基于毫米波和5G组件的宽边耦合互补裂环谐振器的全平面慢波衬底集成波导

作者提出了一种新的，受超材料启发的衬底集成波导（SIW），该波导利用宽边耦合互补开口环谐振器（BC-CSRR）而不是金属化的通孔，将传播限制在引导通道内。由于BC-CSRR的共振行为，以简单有效的方式实现了平面内传播的阻止。最终的波导是通过使用两行CSRR而不是每行过孔来合成的，从而提供了一种完全平面，易于制造且经济高效的解决方案。这种新型波导具有出色的传播特性，损耗接近传统的SIW损耗，为实现用于毫米波应用的低成本平面组件提供了极有希望的平台。为了进一步确认实施基于CSRR的SIW组件的潜力，
