Abstract : The spherical near-field measurement technique is a convenient and economical method for testing antennas. It is particularly useful for electrically small antennas at low frequencies. It requires much less real estate than conventional far-field ranges and yields more accurate results in a more controlled and secure environment. The spherical near-field measurement technique can be used to test antennas too large in physical size for the compact range technique and, unlike other near-field measurement techniques, it permits the use of standard spherical coordinate positioners. The most serious disadvantage of spherical near-field testing is the time required to perform a test.
