Here is the Antenna Aperture formula which helps you to calculate the antenna aperture efficiency on your own. Antenna Aperture Efficiency formula needs values of Electric Current Density, Electric Current Density for 1st element, Wave Length, Radius of Circular Aperture, Distance of the observation point from the Origin, Coordinate Angle 1 and Coordinate Angle 2. The antenna gain shown in top line of the results is the on-axis gain. The results are increasingly approximate beyond the -3 dB contour.

Antenna Efficiency calculator uses antenna efficiency=radiation power/total input power to calculate the antenna efficiency, The Antenna Efficiency formula is defined as the ratio of power radiated (Prad) by the antenna to the power supplied (Ps) to the antenna. Antenna Efficiency Calculator. This tool calculates the efficiency of a satellite antenna based on the aperture, suggested gain and frequency. First, determine the efficiency. Measure the electrical efficiency of the antenna. Next, determine the wave length.

This CalcTown calculator calculates the efficiency of a parabolic antenna given its aperture, gain and wavelength of radio waves. Gain (dBi) The ratio of the signal received or transmitted by a given antenna as compared to an isotropic or dipole antenna. Antenna gain can only be achieved  Antenna gain is found on the basis of Efficiency, Wave Length and Physical Aperture Area. In other words, the antenna gain is defined as the ratio of the power  The calculator will calculate the Antenna Gain for given values of efficiency, wave length, physical aperture area. The relative increase in radiation at the  Input: dish diameter and frequency, output antenna beamwidth and gain. Antenna beamwidth calculator. Enter the diameter of your parabolic dish in m  The concept of antenna efficiency is introduced.
