Mobile phone MIMO antenna array miniaturization-based low SAR research in the combined EMF.

AI: Melanie Research RF Safe Research Library Jan 1, 2026 CONCERN MEDIUM

This engineering/simulation study evaluates tissue SAR from a smartphone operating under single-frequency versus combined (simultaneous 4G and 5G) RF exposure scenarios using multi-pose human models. It reports that peak SAR in various tissues under multi-frequency exposure was 1.02 to 15.85 times higher than under single-frequency exposure. The authors also state that a miniaturized MIMO antenna array can significantly reduce user SAR, though the abstract does not quantify the reduction.

Key points

  • The work focuses on combined RF exposure from simultaneous 4G and 5G operation rather than a single frequency.
  • A miniaturized mobile phone MIMO antenna array is used as the simulated radiation source.
  • Multi-pose human models are used to represent practical smartphone usage scenarios.
  • Peak tissue SAR under multi-frequency exposure is reported as 1.02 to 15.85 times higher than under single-frequency exposure.
  • The authors report that antenna array miniaturization can significantly reduce SAR absorbed by users.
  • The abstract does not provide specific frequencies, absolute SAR values, or detailed modeling parameters.
