Abstract

This research presents the design and analysis of a Substrate Integrated Waveguide (SIW) based slot antenna for high-frequency microwave applications. The antenna structure is developed on a Rogers 5880 substrate with a relative permittivity (εr) of 4.4 and a thickness of 0.6 mm, offering low dielectric losses and stable performance. The SIW cavity is formed using periodic metallic vias with a radius of 0.25 mm and a pitch of 0.8 mm, ensuring effective confinement of the guided wave. A longitudinal slot is etched on the top metallic plane to enable efficient radiation. The overall dimensions of the SIW are 17 mm in length and 8 mm in width, making the antenna compact and suitable for integration in planar circuits. The proposed SIW slot antenna exhibits desirable characteristics such as directional radiation, low profile, and high efficiency, making it promising for applications in wireless communication, radar systems, and compact RF front-ends.
