EVALUATION METHOD
                                                   2
Transmission formula: Pd = (Pout*G)/(4*pi*r )
Where
                                2
Pd = power density in mW/cm , 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
