RF Power Density Calculator

Electrical
1 minute

Determine the power density based on the given values of power, gain, and distance. Suitable for radio frequency (RF) applications and electromagnetic field analysis.

Easily calculate the real power and volt-ampere reactive (VAR) by the input voltage and current values. Suitable for both single-phase and three-phase power systems, this calculator helps determine the actual power and reactive power.

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

    Where:

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