## Formula:

### Current (I) = I mSin(β(L - |z|) )

### Electric Wave (Eθ) = ( 60 × Im / r ) × [ ( Cos (β L Cos&theta) - Cos(βL) ) / Sinθ ]

### Magnetic Wave (HΦ) = ( Im / 2 πr ) ×[ ( Cos (βL Cos &theta) - Cos(βL) ) / Sin θ ]

### 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
