Abstract :
This paper presents a part of a whole study dedicated to the design of an indoor near-field antenna measurement system in VHF range. During this study a new wide band probe covering the 50 to 400 MHz bandwidth was developed, manufactured and characterized. The paper will focus on the use of post-processing techniques to improve measurement results. Measurements have been done in two different systems. Results are given to show the capability of Time Domain filtering and Equivalent Current Approach to reduce ripples due to reflections and truncation effect.
