摘要
A method for computing the far-field pattern of an antenna under test (AUT) from near-field data is presented. Based on the equivalence principle, the A UT is replaced by equivalent magnetic surface currents, whose components are optimized using microgenetic algorithms. Results of reconstructed fair-field patterns from synthetic near,field samples, a comparison to the approach using classical methods, and an analysis of the method's performance and limitations are included.
