Design and analysis of a substrate Integrated Waveguide Antenna Using Ceramic Vias for Bandwidth Improvement

This paper is associated with the substrate integrated waveguide (siw) antenna with two different types of vias such as copper and ceramic material. The dielectric constant of the ceramic vias is 20.9. This paper's main aim is to improve the bandwidth of the antenna using ceramic vias compared to copper vias. Hence the performance parameters of the antenna have been analyzed with copper and ceramic vias in terms of the amount of power lunching into the antenna and bandwidth of the operating frequency at L, S, and G band applications. When the copper vias have used, there are only two resonating bands. but when the ceramic vias have used there are three resonating bands were analyzed. The maximum bandwidth of ceramic vias is about 1170 MHz at the G band when the copper vias are used on the same configuration of the antenna the maximum obtained bandwidth is about 708.60 MHz. More details regarding bandwidth at each band have been analyzed.
