Abstract

There is an explosion of designs of high directive antennas (mainly arrays) based on the use of gap waveguide technology. In most of them, the periodic structure used as Electromagnetic Band Gap (EBG) to control the leakage is the Bed of Nails (BoN). We present here another option where glide-symmetrical holes are used as EBG to design Groove Gap Waveguide (GGWG) based antennas. The use of this unit cell that is much bigger than the pins is beneficial for the manufacturing aspects but poses some challenges in the design of compact components or arrays. Two examples of antenna designs will be presented, one of them includes the design of a compact 1 to 4 power divider. Both of them are experimentally verified.
