Antenna measurement systems using multi-probe technology

Modern antennas and applications are expanding the frequency range towards both lower and higher frequencies while demanding very rapid development and testing cycles. A fast, reliable and accurate way to exhaustively determine antenna and device performance is based on near-field measurement techniques combined with probe array technology. This paper reviews recent developments in multi probe antenna measurements technology and show new application examples. In particular, the results of a challenging measurement of a VHF low-directive antenna performed in a hemispherical multi-probe system are reported.
