Design and Implementation of Substrate Integrated Waveguide for 5G Applications

This study analyses Substrate-integrated waveguides (SIW) using design, simulation, and performance evaluation over a frequency range of 26 GHz to 36 GHz. The structural diagram details a rectangular structure with perforations along its longer edges. The S-parameter plot shows good impedance matching at ports with high isolation between them. The VSWR plot indicates moderate to good impedance matching, with values ranging from approximately 1.2 to 3.5. The SIW highest field intensity is observed near the perforations and edges. Simulation results correlate field patterns with performance characteristics. The device demonstrates minimal reflection at the specific frequencies, enhancing transmission efficiency.
