Аналіз сучасних діелектричних матеріалів та перспективи їх використання в мікросмужкових сенсорах гігагерцового діапазону

Abstract

This study examines dielectric materials for microstrip sensors operating in the gigahertz range (1–100 GHz), focusing on their impact on sensitivity, losses, and stability. Traditional materials like FR-4 and alumina (Al₂O₃) are compared with advanced low-loss polymers (PTFE, Rogers 4350B), metamaterials, and nanomaterials. The analysis highlights that while FR-4 has high losses, modern materials enhance impedance matching, minimize attenuation, and improve sensor performance in high-frequency applications.
