How to Calculate Average Power Density of Half-Wave Dipole?
Average Power Density of Half-Wave Dipole calculator uses Average Power Density = (0.609*Intrinsic Impedance of Medium*Amplitude of Oscillating Current^2)/(4*pi^2*Radial Distance from Antenna^2)*sin((((Angular Frequency of Half Wave Dipole*Time)-(pi/Length of Antenna)*Radial Distance from Antenna))*pi/180)^2 to calculate the Average Power Density, Average Power Density of Half-Wave Dipole is the radiated power per unit area, averaged over a spherical surface, typically calculated at a distance much greater than the wavelength. Average Power Density is denoted by [Pr]_{avg} symbol.
How to calculate Average Power Density of Half-Wave Dipole using this online calculator? To use this online calculator for Average Power Density of Half-Wave Dipole, enter Intrinsic Impedance of Medium (η_{hwd}), Amplitude of Oscillating Current (I_{o}), Radial Distance from Antenna (r_{hwd}), Angular Frequency of Half Wave Dipole (W_{hwd}), Time (t) & Length of Antenna (L_{hwd}) and hit the calculate button. Here is how the Average Power Density of Half-Wave Dipole calculation can be explained with given input values -> 73.23764 = (0.609*377*5^2)/(4*pi^2*0.5^2)*sin((((62800000*0.001)-(pi/2)*0.5))*pi/180)^2.
