Power Density & Field Level (Far Field)

Calculate electric field strength and the corresponding power density from transmitter power, antenna gain, and distance under idealized free-space far-field conditions.

Result: —

Formulas: E = √(30 × P × G) / d
S = E² / 377

Model assumption: idealized free-space far-field propagation, with antenna gain in the direction of the point considered. Reflections, obstruction, cable losses, and near-field effects are not included.

The results are engineering quantities for an idealized far-field model. They do not replace measurements or EMC, exposure, or safety assessments. Actual values may differ due to antenna patterns, losses, reflections, and obstruction.
