Design of substrate integrated waveguide to improve antenna performances for 5G mobile communication application

Abstract

In this paper, a new design of substrate integrated waveguide was developed to improve the gain performance of microstrip antennas for 5G antenna applications. The antenna and substrate integrated waveguide ware designed at the frequency 28 GHz millimeter-wave band. The design of substrate integrated waveguide was developed by design an H-slot structure without a gap in the substrate layer to provide better matching impedance and reduce the loss of surface wave microstrip antenna. This study was conducted with a research and development approach through the calculation of the H-slot structure on substrate integrated waveguide and simulated by using antenna design software simulation. The numerical result shows that the new design approach for the H-slot structure without gap model was improved antenna gain and antenna size. This result has shown significant improvement compared to the circular antenna design without substrate integrated waveguide.
