Array of Horns Fed by a Transverse Slotted Groove Gap Waveguide at 28 GHz

Blog Article

An array of low profile horns fed by transverse slots on a groove gap waveguide (GGWG) is presented.The GGWG is implemented with glide symmetrical holes and the design frequency is 28 GHz.The low profile horns are integrated in the same waveguide wall cga 200 to cga 510 adapter as the slots.The designed antenna is a linear array of these horns but the solution can be easily extended to a planar array.Experimental results support this work.

The designed antenna is a good candidate for applications related to 5G technologies where medium to high gains as well cent dyyni as high efficiencies are required and reasonable manufacturing costs are demanded.
