Method and Implementations to Measure the Absorbed Power Density

We propose a dosimetric compliance test method and implementation with absorbed power density ($\mathrm{S}_{ab}$) limits in the millimeter-wave frequency range. Compliance with the new international exposure limit, $\mathrm{S}_{ab}$ is crucial for the introduction of 5G millimeter-wave communication systems worldwide. The proposed implementation can cover 10 GHz - 30 GHz $\mathrm{S}_{ab}$ measurements with an uncertainty $< 1.7\ \text{dB}\ (\mathrm{k}=2)$ and represents a realistic load to the transmitter during the test. The proposed method integrates with commercially available specific absorption rate (SAR) scanners.
