Antenna Aperture Calculator
English

Antenna Aperture is the assessment of the efficiency of an antenna at its transmitting and receiving radio waves. An aperture efficiency is a number without any dimension, usually reported as a percentage. Effective aperture is represented as Ae and physical aperture is represented as Ap. For horn and reflector antennas, the aperture efficiency falls in the range of 50% to 80%. Use this Antenna aperture calculator to calculate antenna aperture efficiency at two different angles.

Formula

Eθ= [ ( j ×k ×a2×E0×e-jkr ) / r ] × Sin φ [ ( J1×k×a×Sinθ) / k×a ×Sinθ] φ = [ ( j×k×a2×E0×e-jkr ) / r ] ×(Cosθ×Cosφ) [(J1×k×a×Sinθ) / k×a×Sinθ] Where, k = 2 π / λ λ = Wave Length E0 = 8.8541878176 ×10-12F/m (electric constant) θ = Coordinate Angle 1 φ = Coordinate Angle 2 a = Radius of Circular Aperture r = Distance of the observation point from the Origin j = Electric Current Density J1 = Electric Current Density for 1st element
