The invention discloses a stacked decoupling network, and the network comprises a substrate, wherein
metal through holes distributed in a
square array mode are formed in the substrate, and
metal strips are further distributed on the upper layer and the lower layer of the substrate and used for connecting the adjacent
metal through holes into a whole to form a square unit; the the
metal strips aredistributed up and down between the adjacent metal through holes in a staggered manner. Four connecting arms extend from four end corners of the square unit to the left side and the right side, each connecting arm is also composed of a metal through hole and a metal strip, and the connecting mode is the same as that of the square unit. The metal through holes in the substrate are distributed in abroken line shape on each side of the
square array, and the upper layer and the lower layer of the corresponding substrate are connected with the
metal strips of the adjacent metal through holes in abroken line shape. According to the core principle of an existing orthogonal
hybrid network, the orthogonal
hybrid network of a folding structure is designed, a
chip is integrated through the low-temperature co-fired
ceramic technology, and the
chip generates a decoupling effect within a certain
frequency band and is used for decoupling among multi-antenna systems.
