Two-Layered Microwave Absorber Laminated with Magnetic Composites for Intelligent Transport System

Abstract:

Two-layered microwave absorbers are designed for the achievement of low reflection coefficient for wide angles of oblique incidence at the frequency of intelligent transport system (5.9 GHz). Magnetic composite sheets were fabricated with carbonyl iron (CI) and Co₂Z hexaferrite particles in rubber matrix. On the basis of transmission line theory, reflection loss has been calculated with variation of incident angles for both transverse electric (TE) and transverse magnetic (TM) polarization. The minimum reflection loss (less than-20 dB) is predicted at 5.9 GHz for the laminated composites of Co₂Z/CI. At the optimum thickness of the composite layers, a low value of reflection loss (less than-10 dB) is predicted for wide incidence angles up to 60°. The two-layer composites laminate can be proposed as the high potential microwave absorbers for improvement of electromagnetic environment in ITS operation.
