Enhanced Radar Cross-section for W-Band Corner reflectors using Ceramic Additive Manufacturing

Corner reflectors (CR), especially when combined with information coding, are potential candidates for radar beacon applications, which could be used for the self-localization of autonomous vehicles. In order to further improve the radar cross-section (RCS) of such devices, we have evaluated additively manufactured filled corner reflectors made of alumina in comparison to classical metal based CRs in the W-Band. The ceramic CRs were implemented using Lithography-based Ceramic Manufacturing (LCM), which is a novel high quality, high-resolution technology gaining traction in the RF community.
