Ka-band planar slotted waveguide array based on groove gap waveguide technology with a glide-symmetric holey metasurface

Abstract The design of a planar slot array in groove gap waveguide technology implemented by glide-symmetric holes as Electromagnetic Band Gap structure is here presented. Despite the advantages of using holes instead of pins in terms of manufacturing simplicity and cost,the larger size of the holes...
