Abstract—This article designs, tests, and produces a substrate integrated waveguide based antenna with copper patches in the micro strip in a totally planar construction utilising microstrip technology. The performances of this SIW antenna, as well as geometrical antenna aspects, are investigated in the X-band at frequencies ranging from 5 to 10 GHz. The efficiency and directivity of the substrate integrated waveguide antenna have been improved, and the side lobe level has been increased, making it highly promising. SIW technology seems to be the most viable option for millimeter-wave integrated circuits and systems in the next decade. This article gives an overview of SIW technology research in academia and industry, as well as its current state and future potential. The development of numerical tools for SIW component modelling and design, as well as the investigation of new compact and broadband interconnects and the discovery of design solutions for loss reduction, are all current research priorities. It consists of two connected quarter-mode SIW resonant cavities and one half-mode SIW resonant cavity. This groundbreaking technology combines a considerable bandwidth boost with a tiny footprint and existing PCB manufacturing procedures at a cheap cost, making it ideal for 5G high-speed wireless applications. SIW technology provides a robust antenna basis, enabling for the integration of high-density active electronics without the possibility of damaging coupling.
