Title:
ANTENNA BEAM DIRECTIVITY DEVICE AND ANTENNA BEAM DIRECTIVITY METHOD
Document Type and Number:
WIPO Patent Application WO/2011/068140
Kind Code:
A1
Abstract:
Provided are an antenna beam directivity device and an antenna beam directivity method by which directivity accuracy of the antenna beam can be improved without adding a large scale device. The antenna beam directivity device having an array power feeding system is provided with an input signal vector generation means for generating an input signal vector from an input signal, a weight vector holding means for holding a weight vector, a weight correction means for correcting the weight vector so that, on the basis of an inner product value of the input signal vector and the weight vector, the inner product value with respect to a reference signal becomes a value equal to a first value, and a beam forming unit for forming a null beam in the direction of the reference signal.
