Low-Cost Automated Stand for Directivity Pattern Measurements of Small-Sized Aperture Antennas

The results of the development of a low-cost automated setup for measuring the radiation patterns (RP) of small-sized aperture antennas, which makes it possible to carry out an experimental estimation of the RP in the E- and H-planes, are presented. The obtained results of measurements of the RP of dual-reflector antennas with axisymmetric symmetric Cassegrain geometry and a corrugated conical horn are compared with the results of numerical simulation and direct calculation of the RP using the aperture method.
