              Friis transmission formula: Pd=(Pout*G)\(4*pi*R2)
             Where
             Pd= Power density in mW/cm2
             Pout=output power to antenna in Mw
             G= gain of antenna in linear scale
             Pi=3.1416
             R= distance between observation point and center of the radiator in cm
             Pd the limit of MPE, 1mW/cm2. If we know the maximum gain of the antenna
             and total power input to the antenna, through the calculation, we will know the
             distance where the MPE limit is reached.
