An Integrated substrate Waveguide (SIW) backed slot antenna for a 5G millimeter (mm) wave band is discussed and simulated in the present research. The presented antenna has a wide frequency bandwidth of 3.9 GHz (18.51%) and a peak gain of 7.48 dB. Two equal-sized L-type slots are engraved on the ground plane, and two shorting vias other than the SIW cavity vias are added below the slots to achieve wideband characteristics. A low-profile, 0.787 mm thick RT/Duroid 5880 used as the substrate. The antenna operates in the spectrum for 5G communication from 25.1 GHz to 29 GHz. In the presented research, the antenna's analysis, performance and design aspects are discussed and investigated using simulated results on HFSS. The antenna is excited with a 50 Ω microstrip transmission line to SIW transition taper for proper impedance matching to achieve superior electrical performance. The proposed antenna shows dual resonating features at 26.1 GHz and 28.5 GHz. The dimension of the complete antenna is 14×18×0.787 mm3. The reflection coefficient (S11), current density, and peak gain of the proposed antenna give insight into the antenna's working. The suggested antenna is ideal for 5G applications because of its broad spectral coverage, small size, and high gain. [ABSTRACT FROM AUTHOR]
