Dipole Antenna Formula

Average radiated power density (Pd) = (15* Im2 / Ï€r2) ×[ ( Cos (βL Cos&theta) - Cos(βL) ) / Sinθ ] 2

Magnetic Wave (Hφ) = (Im / 2 πr ) *[ ( Cos (βL Cos&theta) - Cos(βL) ) / Sinθ ]

Electric Wave (Eθ) = (60 * Im / r) * [(Cos (βL Cos&theta) - Cos(βL) ) / Sinθ

Current (I) = Im Sin (β(L - |z|) )

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