Radar Cross-Section of Ceramic Corner Reflectors in the W-Band Fabricated With the LCM-Method

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, additively manufactured filled corner reflectors (FCR) made of ceramics in comparison to classical metal based CRs in the W-Band, were evaluated. 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.
