Assessment of RF EMF Exposure to Car Driver from Monopole Array Antennas in V2V Communications Considering Thermal Characteristics
This modeling study assessed RF-EMF exposure from a 5.9 GHz V2V monopole array antenna integrated into a car roof shark-fin antenna. Using COMSOL simulations with an adult male body model inside a vehicle, the authors estimated localized and whole-body SAR and associated core temperature rise over a 30 min averaging period. Reported SAR and temperature rise values were below ICNIRP occupational thermal-based restrictions, leading the authors to conclude the exposure does not pose a threat under the studied conditions.
Key points
- The study models a 5.9 GHz V2V monopole array antenna integrated into a vehicle roof antenna.
- COMSOL Multiphysics simulations estimate SAR in head and body regions for an adult male model inside a 3D vehicle model.
- Worst-case head SAR is reported as 0.981 W/kg, described as below the ICNIRP localized limit.
- Whole-body average SAR is reported as 0.008728 W/kg, described as below the ICNIRP whole-body limit.
- A 30 min average core temperature rise of 0.055°C is reported and described as below the ICNIRP limit.
- The conclusion is based on comparison to existing thermal-based safety standards rather than direct health outcome measurements.
