Implementation of UC-EBG structure for 60 GHz gridded parasitic patch stacked microstrip antenna

A uniplanar-compact electromagnetic band-gap (UC-EBG) structure is implemented at 60 GHz on a conventional PTFE (polytetrafluoroethylene) substrate. The structure surrounds a stacked microstrip antenna with gridded parasitic patch. The UC-EBG implementation results in about 5 dB decrease in the antenna E-plane normalized radiation pattern for angles along the substrate. The measured antenna gain increase at 60 GHz is 1.5 dB. Measured results are in good agreement with simulation. The design can be used for fifth generation (5G) wireless communication systems to reduce the antenna interference with other components.
