METHOD FOR SHAPING ANTENNA-ARRAY MULTILOBE DIRECTIVITY PATTERNS Russian patent published in 2007 - IPC H01Q3/26 

FIELD: antenna engineering.

SUBSTANCE: proposed method for shaping multilobe directivity patterns of antenna array depends on weighing signals received by each radiator followed by their summing that includes finding weighting coefficient as master vector of Hermitean-form beam corresponding to maximal characteristic number of beam; information about directions in which main lobes of directivity pattern are oriented, their relative level, as well as information about desired values of phase pattern in directions of generated lobes are used to determine master vector of Hermitean-form beam; in this connection complex weighting coefficients including desired values of reverse-polarity phase pattern are used in weighing directivity pattern values in direction of generated lobes. Chosen as first Hermitean form of beam is module square of weighted sum of directivity pattern values in directions of generated lobes and as second one is mean value of directivity pattern with respect to power.

EFFECT: ability of regulating phase pattern in directions of main lobes when shaping multilobe directivity patterns with desired positions and levels of these lobes.
