Purpose and goal
The project aims to design, fabricate and validate a monolithic, metallic frequency selective surface (FSS) with polarization capability for future 6G systems. The goal is to demonstrate the feasibility of conformal LPBF-fabricated FSS that enables circular polarization from linearly polarized antennas – a key component for robust, scalable 6G solutions at high frequencies.
Expected effects and result
The project delivers validated FSS prototypes fabricated with LPBF, with measured electromagnetic performance that meets 6G eligibility requirements. The results are expected to demonstrate that additive manufacturing enables conformal, broadband polarization surfaces with industrial relevance. In the long term, this contributes to cost-effective antenna solutions for 6G infrastructure and strengthens Swedish expertise in advanced RF manufacturing.
Planned approach and implementation
The project follows an iterative prototyping cycle: initially, a planar polarizing FSS, in one or more layers, is designed and validated to establish the electromagnetic concept. This is then developed into a conformal geometry adapted for curved platforms. Each iteration includes EM design, adaptation to LPBF manufacturing constraints, and experimental RF validation. The work is conducted in close collaboration between academia and industry.
