Equation from page 18 of OET Bulletin 65, Edition 97-01
PG ( Ed )²
S= PG =
4pR 2 (formula 1) 30 (formula 2)

where: S = power density
P = power input to the antenna
G = power gain of the antenna in the direction of interest relative to an isotropic radiator
R = distance to the center of radiation of the antenna

PG = Effective Isotropic Radiated Power (EIRP)
E = Electric field measured at distance R distance
d = measurment distance
