Additively Manufactured S/X Dual-Band Antenna

Additively manufactured antennas could offer substantial competitive advantages, even in defence market, thanks to its design flexibility, faster development and production cycles. This article details the first documented use of Radix™ 4.9 Dk Exp. resin to design an S/X dual-band antenna. The paper presents the opportunity to print substrates in Digital Light Processing (DLP) technology with synthetic/variable dielectric constant and its potential for future dual-band radar array antennas. To prove the feasibility of the proposed technology, the design of an additively manufactured S/X dual-band antenna Proof of Concept (POC) is shown and the comparison between electromagnetic (EM) simulations and measurements are detailed.
