The IEEE Antennas and Propagation Society supports the research project “Spherical Modal Expansion from an Arbitrary Closed Surface for Near-Field Antenna Measurements” from Rasmus Cornelius.
The aim of the project is to develop and evaluate a new algorithm that will allow the transformation of the near-field antenna measurement data acquired on any closed surface into a spherical mode spectrum and consequently three-dimensional far-field radiation pattern.
This is motivated by the future development of wireless communication systems like 5G, increasing the demand for antenna measurements. Given the high cost of antenna measurements cheaper, more robust but still comprehensive measurement techniques are needed.
The proposed algorithm will not require exact spherical measurement positions (usually < lambda / 50) allowing faster and simpler scanning designs. It will allow the transformation origin to be placed on arbitrary location, minimizing the number of measurement points and reducing possible interferences in imperfect anechoic chambers. The measurement with arbitrary surfaces is expected to open new research avenues, with plethora of possible applications. It will allow faster and more accurate antenna measurements, saving costs of the overall design procedure.
