The subject of antenna measurements is one which has undergone revolutionary changes in recent years, in particular within space applications, where high demands are placed upon antenna design and construction.This book represents the specific measurement technique known as the spherical near-field method. The theoretical treatment of the method is detailed but of sufficient generality to make the book useful as a basis for further research on near-field measurements and antenna coupling problems. Practical aspects of antenna test ranges, data processing schemes and measurement procedures are described. Other topics covered are measurement error analysis and generation of plane wave fields.The authors draw on the experience from the development, sponsored by the European Space Agency, of one of the first spherical near-field test ranges. They have contributed to the establishment of spherical near-field testing as a highly accurate and versatile method, currently under implementation at test ranges worldwide.

Jesper E. Hansen received his MSc and PhD degrees in electrical engineering from TUD in 1957 and 1965 respectively. Since 1966 he has been an associate professor and head of the antenna group at the Electromagnetics Institute, TUD. He has been project manager for a number of research projects carried out for the European Space Agency within the areas of spacecraft antennas and spherical near-field antenna measurements.Jørgen Hald received his MSc and PhD degrees in electrical engineering from the Technical University of Denmark (TUD) in 1978 and 1984 respectively, with antenna theory and numerical optimisation as his main subject areas. Since 1982 he has been with Brüel & Kjaer Industry A/S, working with acoustic nearfield measurement techniques, in particular measurement of acoustic intensity and near-field acoustic holography.Frank Jensen received his MSc and PhD degrees in electrical engineering from TUD in 1968 and 1971 respectively. Since 1982, he has been with TICRA, Copenhagen, where he works in the field of satellite antennas. He has special experience within near-field measurement techniques, design and construction of dual polarised high-precision measurement probes, and interaction between satellite antennas and the structures on which they are mounted.Flemming Holm Larsen received his MSc and PhD degrees in electrical engineering from TUD in 1973 and 1982 respectively. At present, he is an assistant professor at the TUD Electromagnetics Institute, where he has been involved in research on antenna measurements since 1974. In particular, he has developed a number of computer programs for spherical near-field far-field transformation with probe correction.
