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 was designed at freq 28 GHz millimeter-wave band. The design of substrate integrated waveguide was developed by design an H-slot structure without gap in the substrate layer to provide better matching impedance and reduce 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 new design of H-slot structure without gap model was improved antenna return loss more than 8 dB and bandwidth more than 1 GHz . This result has shown a significant improvement compared to antenna design without using substrate integrated waveguide.
