Power Density Case Study for 5G mmWave Array Antennas

As 5G millimeter wave (mmWave) wireless device involves some new technologies, such as beamforming, the radiofrequency (RF) exposure compliance test for mmWave is significantly complicated. In order to shorten period terminals, relevant regulatory authorities recommend a combination of numerical simulation and measurements demonstrate compliance. To verify feasibility this method, RF conducted in paper was reverse procedure according IEEE (the Institute Electrical Electronics Engineers) standards. First, actual under various conditions, including different beam configurations, distances, input power levels, duty cycle, nonpeak directions, were performed, changing trend PD over testing conditions analyzed. Then one dual-polarized patch antenna array selected analysis. The method proposed standards proved through comparison results experiment
