RF Power Density Calculator

An antenna can radiate power in all the directions. It is nothing but the rate of change of energy transfer. Power density is also referred as volume power density or volume specific power. It is an amount of power per unit time. Use our RF power density calculator to calculate the power density at a given distance, output power and antenna gain. Power density is the measure of power from the antenna to a defined distance.

Radio frequency power density can be easily measured by using the power input, power gain, distance to the center of antenna and pi value. RF power density calculator estimates the density of power of radio frequency waves.
