In recent years, efforts have focused on SIGW technology. The technology is claimed to be an effective step towards improving the performance of waveguides, especially at high frequencies, by linking the two research disciplines SIW and GW. The motivation for this research stems from its application in today's telecommunications market. From the first generation to the fifth generation, cellular telecommunications has a special and decisive position in this market and therefore, as an upstream industry, it has created various research and manufacturing opportunities in various fields. Since communication technology in cellular communication is wireless communication, it can be boldly said that the radio access network is the ossification of a cellular network and the cornerstone of a network consisting of radio communications is the filter. The introduction of SIGW technology in this research is important because with the design of the fifth generation of telecommunications and migration to high frequencies, the construction of GW devices with conventional methods faces major challenges. Dielectric losses in SIW also increase losses at these frequencies. This dissertation compares SIW, GW and SIGW waveguides, as well as the applications of each of them. It feels. The main goal of this project is to design and build a transition from grooved SIGW to microstrip lines. Also in this project, the SIGW intermediate filter will be designed and this filter will be integrated with the proposed transition. It should be noted that all simulations have been performed in HFSS software and the results of this structure are given in this dissertation.
