Cavities built into the vehicle chassis have recently emerged as receptacle for hidden antennas. In the automotive sector they potentially replace the roof mounted sharkfin antenna modules. Simulation models for chassis antenna cavities are critical, because they must both accurately predict antenna performance, while staying computationally reasonable. Moreover, if the chassis of electric cars, airplanes and boats are built with carbon fiber reinforced polymer, then a model for the composite laminate is required. In this paper a simple simulation model for chassis antenna cavities is developed. The carbon fiber composite material is modeled as a linear, homogeneous and isotropic conductor, and several cavity geometry details are omitted. Simulation results are in good agreement with measurements in the frequency band at 5.9 GHz for intelligent transport systems.

“…An automotive roof mounted antenna module (shark-fin) is measured on a CFRP car roof in [26]. An antenna cavity for integration into CFRP sheets, such as aircraft skin panels or car chassis, is proposed and prototyped in [27]. In vehicular applications the antenna cavity can be manufactured as part of a carbon fiber reinforced car roof as is described in [28].…”

A carbon fiber reinforced polymer (CFRP) laminate, with the top layer consisting of shredded fibers, is proposed and manufactured. The shredded fibers are aligned randomly on the surface to achieve a more isotropic conductivity, as is desired in antenna applications. Moreover, fiber shreds can be recycled from carbon fiber composites. Conductivity, permittivity, and permeability are obtained with the Nicolson-Ross-Weir method from material samples measured inside rectangular waveguides in the frequency range of 4 to 6 GHz. The decrease in material anisotropy results in negligible influence on antennas. This is shown by measuring the proposed CFRP as ground plane material for both a narrowband wire monopole antenna for 5.9 GHz and an ultrawideband conical monopole antenna for 1-10 GHz. For comparison, all measurements are repeated with a twill-weave CFRP.
