Abstract. In this paper we present a radiation pattern reconstruction using near-field amplitude measurements of electric field. An algorithm for the solution of the measurement task is given. The results of the radiation pattern reconstruction using the proposed algorithm are presented. Moreover, these results are compared with the ones obtained by a classical method of measuring radiation pattern in far-field of the antenna under test. We study the dependence of the amplitude measurement information quality on the accuracy of the discussed method.
Keywords: near-field region, NF-FF transformation, two planes, aperture antenna, amplitude measurements, optimization methods, ill-posed problem.
