Characterization of small antennas for hearing aids by several measurement techniques

Paper in proceeding, 2010

Characteristics of electrically small loop antennas were measured by different techniques and the results were compared in-between. The techniques employed were: a single-probe spherical near-field technique, a multi-probe spherical near-field technique, a reverberation chamber, and a Wheeler cap technique. The results were compared with regard to the measurement accuracy, measurement speed, and applicability for characterization of small antennas in complex application environment.
