Abstract

This paper presents a compact sinuous spiral antenna integrated with a soft surface structure, featuring a square ring placed directly above a Substrate Integrated Waveguide (SIW)-backed cavity, designed for 60 GHz frequency applications. The antenna design achieves a compact size while delivering a wide bandwidth, approximately 16 GHz, covering the entire 60 GHz unlicensed band. It achieves a peak gain of 14 dBi at 70 GHz and a gain above 8 dBi for the rest of the operating band, making it an excellent choice for Millimeter-Wave (mm-Wave) communication systems. Combining the soft surface structure and SIW cavity enhances radiation efficiency and performance. The proposed design effectively suppresses surface wave propagation, minimizing losses and improving radiation characteristics. The simulation results demonstrate the antenna's effectiveness for next-generation wireless communication systems, including 5G and high-speed networks.
