| description | This study explores the potential applications of carbon fiber composite material for structural antennas. Carbon fiber composite materials provide excellent specific strength and stiffness; however, their electrical properties, such as conductivity, are not well established, especially in the very high-frequency (VHF) range. Knowledge of a material's conductivity is required for electrical performance estimation through simulations. Through combined experimental and simulated analysis of multiple carbon fiber antennas, the effective conductivity for a biaxial weave carbon fiber composite was determined to be between 7000 and 13 000 S/m in the VHF spectrum. Carbon fiber antenna performance is found to be particularly sensitive to the contact between the carbon fibers and the copper feed; however, radiation efficiencies (REs) of carbon fiber composite antennas are found to be within 2%-10% of a geometrically identical copper antenna, and their bandwidths are nearly identical. The electrical performance of carbon fiber composite antennas demonstrates significant promise for structural antenna applications in the VHF range. |
