Abstract :
The paper presents a near-field antenna measurements solution using a fiber-optic techniques to improve phase measurements accuracy. The main problem in the near-field antenna measurements is phase distortions which result from the changes of cable geometry during the measurements. Measurement solution has been proposed, allowing to illuminate phase errors, and consequently, to enhance measurement accuracy in comparison to conventional technique.
