Just copy and paste the below code to your webpage where you want to display this calculator.



Formula
Current (I) = Im Sin( β(L - |z|) )
Electric Wave (Eθ) = ( 60 ×Im / r ) ×[ ( Cos (βL Cos&theta) - Cos(βL) ) / Sinθ ]
Magnetic Wave (HΦ) = ( Im / 2 πr ) ×[ ( Cos (βL Cos&theta) - Cos(βL) ) / Sinθ ]
Average radiated power density (Pd) = (15× Im2 / πr2 ) ×[ ( Cos (βL Cos&theta) - Cos(βL) ) / Sinθ ] 2

Where,
    β = 2π / λ
    λ = Wave Length
    Im = Magnetic Current
    L = Half Antenna Length
    r = radius
    θ = Angle
