For getting power density at 20 ㎝ separation in above table, following formula was used. S = P * G / (4π * R²) = 0.249 * 1.71 / (4 * π * 20^2) = 0.000 08 Where: S = Power Density, P = Power input to the external antenna (Output power from the EUT antenna port (㏈m) – cable loss (㏈)), G = Gain of Transmit Antenna (linear gain), R = Distance from Transmitting Antenna - END -
