Özet

This paper presents a low-profile dielectric checker-board scattering surface designed to provide wideband RCS reduction without the use of metallic patterns. The surface is fabricated from a single 3D-printed material, where the dielectric constant is controlled by adjusting the infill ratio. This approach offers a practical, cost-effective, and scalable solution for RCS reduction by eliminating the need for complex designs and multiple materials. Simulations demonstrate a better than 10 dB monostatic RCS reduction compared to a PEC plate over a broad bandwidth of 78%, covering the frequency range from 10 GHz to 22.9 GHz, with strong performance across the Ku band.
