It exploits a micro Unmanned Aerial Vehicle (UAV) as a far-field test source. The system demonstrated good performance on the copolarization radiation pattern of VHF and UHF antennas. Several results with reference antennas have been published [2, 3]. Further experiments have been performed on the Aperture Array Verification System (AAVS0) array and the Medicina Array Demonstrator (MAD), which also focus on the calibration of a small array and the beam forming. This paper presents two recent experiments performed on a log-periodic antenna at 250 MHz and 350 MHz. Significant results have been achieved for both co- and cross-polarization patterns. Moreover, the symmetry of the test-source pattern has also been demonstrated.ELETTRONICOenConference paper10.1109/ICEAA.2015.72972072-s2.0-84955491928https://ieeexplore.ieee.org/abstract/document/7297207FIS/05 - ASTRONOMIA E ASTROFISICAScienze Fisiche Settori ERC (ERC) di riferimento::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation
