This article proposes a novel high‐performance and compact size diplexer that implemented by the half‐mode substrate integrated waveguide and loaded by complementary split ring resonator. The diplexer operates below the characteristic cutoff frequency of the waveguide. High isolation, low loss, low cost, easy fabrication, miniaturization of size, and integration with other circuits are remarkable attributes of the structure. A higher number of poles and better out of band response causes to give valuable results. Designing steps equivalent circuit, simulation and experimental results are presented. Simulation and measurement results are in good agreement.
