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

What is antenna aperture? Antenna aperture refers to the effective area of an antenna that captures incoming electromagnetic waves. It is a critical parameter in determining the overall performance of the antenna, as it directly affects the received signal strength and the antenna's ability to transmit and receive signals.
