5G mm Wave Shielding with Frequency Selective Surface Employing Centre Offset Swastika Loop Element

.5Gs impact extends to next-generation wireless devices, satellite communication, radar systems, healthcare devices, smart cities, and IoT infrastructure, as well as ensuring electromagnetic compatibility in automotive communication, defense applications, and antenna optimization. This study focuses on designing an FSS optimized for 5G EMI shielding, with specific objectives centered around unit cell miniaturization and characterization under varying angles of impact (θ = 0°, 15°, 30°, 45°, 60°, and 75°). The investigation encompasses the measurement of scattering parameters (S-parameters) for both TE and TM modes, and evaluating the shielding effectiveness. The paper targets on resonant frequency is at 25.99 GHz within the n258 band.
