The Antenna aperture means how effective an antenna is at receiving the power of radio waves.

Electron Gain Formula

Eφ = [ ( j*k*a2*E0*e-jkr ) / r ] *(Cosθ*Cosφ) [(J1*k*a*Sinθ) / k*a*Sinθ]

Eθ = [ ( j*k*a2*E0*e-jkr ) / r ] * Sinφ [ ( J1*k*a*Sinθ) / k*a*Sinθ ]

Where,

E0 = 8.8541878176 * 10-12F/m (electric constant)

J1 = Electric Current Density for 1st element

j = Electric Current Density

r = Distance of the observation point from the Origin

a = Radius of Circular Aperture

λ = Wave Length

k = 2π / λ

θ = Coordinate Angle 1

φ = Coordinate Angle 2
