AP0606-0550 1 Antenna Pattern Correction Technique Based on an Adaptive Array Algorithm Ville Viikari, Student Member, IEEE, Veli-Matti Kolmonen, Jari Salo, Antti V. Räisänen, Fellow, IEEE function of the rotation angle during the second measurement. Abstract— This paper presents an antenna pattern correction The displacement is adjusted so, that at each rotation angle, technique, which is based on an adaptive array algorithm. In the the measurement points form a virtual array, whose array method, the antenna pattern of the antenna under test (AUT) is factor has a peak in the direction of the desired plane wave and measured several times at different positions in the quiet-zone. The corrected antenna pattern is obtained by taking a weighted a null in the main beam direction.
