RADIATION PATTERN RETRIEVAL IN NON-ANECHOIC CHAMBERS USING THE MATRIX PENCIL ALGORITHM

Abstract

In this paper, the Matrix-Pencil method is used to retrieve the radiation pattern of several antennas measured in difierent semi- anechoic scenarios using low directive probes, where the existence of re∞ected contributions can severely disturb the measurement. Starting from data measured in the frequency domain, this method allows the direct path to be identifled and the radiation pattern of the antenna to be retrieved with good accuracy in all the cases under study.
