rf power density calculator

enter the value and click "calculate", the calculation result will be displayed.

the formula given below complies with epa fcc oet notice no 65.
S = ( P × G ) / ( 4 × Pi × R2 )
s = power density
p = power input to the antenna
g = antenna power gain
r = distance from antenna radiation center

enter a value:

antenna input power (p):
mW
antenna power gain (g):
distance to antenna radiation center (r):
cm

calculation result:

power density(s):
mW/cm2
rf power density calculator the rf power density calculator is an online tool for measuring rf power density in electrical and electronic circuits. radio frequency waves are electromagnetic waves that travel along a medium or free space. this calculator uses input values ​​for antenna power gain, radiation distance, and antenna input power to determine rf frequency propagation power density. it can be mathematically deduced by the following formula
