How to Calculate Radiation Resistance of Antenna?
Radiation Resistance of Antenna calculator uses Radiation Resistance = 2*Average Power/Sinusoidal Current^2 to calculate the Radiation Resistance, Radiation Resistance of Antenna is the equivalent resistance that would dissipate the same amount of power as radiated by the antenna, representing the efficiency of power conversion from electrical to electromagnetic form. Radiation Resistance is denoted by R_{rad} symbol.
How to calculate Radiation Resistance of Antenna using this online calculator? To use this online calculator for Radiation Resistance of Antenna, enter Average Power (P_{r}) & Sinusoidal Current (i_{o}) and hit the calculate button. Here is how the Radiation Resistance of Antenna calculation can be explained with given input values -> 6.306173 = 2*63.85/4.5^2.
