Fundamental applicability evaluation of carbon fiber reinforced plastic materials utilized in millimeter-wave antennas

The carbon fiber reinforced plastic (CFRP) materials for the millimeter-wave antenna application are experimentally evaluated. First, the polarization characteristics of the fundamental unidirectional CFRP laminates are measured at W-band. The measured transmission characteristics show that the significant difference depends on the polarization of the incident wave. Second, the CFRP parabolic reflectors with and without chrome plating are measured. The results show almost the same characteristics. From these results, the fundamental applicability of the CFRP laminates utilized in millimeter-wave antennas is confirmed.
