Abstract
An easy-to-use equation is presented to allow for a quick estimate of the beam efficiency of reflector antennae. This estimate includes the effects of edge tapers, feed spillover, random surface errors and central blockage. Attempts are made to determine theoretically the approximate fields on the beam efficiency of the reflector antennae under several simplifying assumptions. In most practical cases the approximations are acceptable. The application of this formula is detailed in a case study, and its accuracy is demonstrated in comparison with a numerical simulation using diffraction analysis. An excellent agreement is found between theoretical and experimental results.
