Averaging Area Of Incident Power Density For Human Exposure From Patch Antenna Arrays

This study discusses an area-averaged incident power density to estimate surface temperature elevation from patch antenna arrays with 4 and 9 elements at the frequencies above 10 GHz. We computationally demonstrate that a smaller averaging area (1 cm(2)) of power density should be considered at the frequency of 30 GHz or higher compared with that at lower frequencies (4 cm(2)).
