Abstract(in English) | As a method for forming the desired directivity, we propose a method based on multiplication of the outputs of multiple weighted sum circuits(WSC), in which all directional constraints are eliminated.This method approximates the desired directivity by eliminating the constraints of WSC that form a single null.Although the approximation of the desired directivity improves the extraction performance, it degrades the suppression performance.In this study, the suppression performance is improved while ensuring the degree of freedom in directivity design by setting a specified error in each WSC. |
