RF Power Density Calculator

Enter value and click on calculate. Result will be displayed.

Formula given below is as per EPA FCC OET Bulletin NO 65.
S = ( P × G ) / ( 4 × Pi × R2 )
S = Power Density
P = Power Input to Antenna
G = Power Gain of Antenna
R = Distance to center of Radiation of Antenna

Enter your values:

Power Input to Antenna (P):
Power Gain of Antenna (G):
Distance to center of Radiation of Antenna (R):


Power Density (S):
RF Power Density Calculator RF power density calculator is an online tool for electrical and electronic circuits to measure the RF Frequency Power Density. RF waves are the electromagnetic waves transmission along a medium or free space. This calculator uses the input values of Antenna power gain, Radiation distance and antenna input power to determine the RF frequency propagation power density. It can be mathematically derived from the following formula
