Sustainable design of UHF bandpass filter : material selection, R-strategies, and mechanical improvement

Abstract

This paper explores how sustainable engineering principles and circular economy strategies can be incorporated into the design of ultra-high frequency (UHF) bandpass filters, which are widely used in communications, radar, and satellite systems. Although traditional RF components play a vital role in signal transmission, their design often ignores environmental and resource efficiency considerations. To address this gap, this study proposes a comprehensive design framework for UHF bandpass filters that is sustainable by combining materials science, life cycle thinking, and mechanical improvement.

This study uses a multidisciplinary approach that includes an extensive literature review, expert interviews with RF engineering professionals, laboratory testing, and advanced numerical simulations using the SolidWorks Sustainability and ANSYS platforms. The study focuses on three key areas: (1) environmentally friendly material selection using multi-criteria weighted models and thermo-mechanical validation; (2) extending product lifecycles through the R9 strategy (Reduce, Reuse, Recycle, Remanufacture); and (3) structural improvements to enhance modularity, disassembly, and recyclability without compromising RF performance.

The study culminates in a practical and replicable sustainable RF filter design framework that balances electrical and mechanical functionality with environmental impact. The study shows that sustainable design is not only technically feasible, but also has strategic value in promoting the transition to eco-efficient engineering systems.
