RF Power Density Calculator

Input Power
Power Gain
Distance to the Center of Antenna

Compute power density using provided power, gain, and distance values. It benefits radio frequency (RF) applications and electromagnetic field analysis.

Effortlessly determine real power and volt-ampere reactive (VAR) through inputting voltage and current values. Applicable to both single-phase and three-phase power systems, this calculator aids in identifying actual power and reactive power.

RF Power Density formula

    \[S = \frac{P \cdot G}{4 \cdot \pi \cdot R^2}\]


  • S = Power Density,
  • P = Power Input,
  • G = Power Gain,
  • R = Distance to the Center of Antenna,
  • PI = 3.14
