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.
