Abstract
In this work, a multiple triangular-slot Substrate Integrated Waveguide (SIW) antenna has been proposed for 5 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> generation mobile communication applications with broadband characteristics. The proposed siw antenna has been realized with three different structures to satisfy the millimeter-wavelength for 5G mobile communication applications on the frequency spectrum. Copper vias have been integrated between ground and patch surfaces, later to introduce triangular slots on the patch element to obtain broadband characteristics with low return loss performance. The Rogers RO4232 (tm) substrate material is used with dielectric relative permittivity 3.2, loss tangent 0.0018 and the thickness of the dielectric medium is 1.6 mm. This design has been simulated on HFSS software. The performance of the antenna is analyzed with the help of the characteristics of return loss, VSWR, bandwidth and its radiation patterns properties. The designed SIW antenna offers a resonating frequency band from 21.80 GHz to 37.34 GHz.
