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.
