Hybrid Glide-Symmetric Unit Cell for Leakage Reduction in Millimeter-Wave PCB Interconnections to Waveguide Components

In this article, we propose a hybrid glide-symmetric metasurface which presents an electromagnetic bandgap (EBG) behavior at the $Ka$ -band. The innovative part of work is nature periodic structure, implemented with holes on two different technologies: printed circuit board (PCB) and metallic waveguide. These avoid propagation in undesired parallel plate created between PCB To demonstrate potential concept, configuration was placed surrounding PCB–waveguide transition -band to reduce leakage by air gaps. A prototype manufactured measured corroborate effectiveness technique losses crosstalk.
