Stacked decoupling network

Abstract

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.

Description

technical field [0001] The invention relates to the field of multi-antenna decoupling, in particular to a stacked decoupling network. Background technique [0002] With the rapid development of mobile communication systems, radio frequency spectrum resources are increasingly scarce, and how to provide higher-quality and faster communication services has become a research hotspot in the fifth-generation mobile communication system (5G). In this context, the multiple-input multiple-output (MIMO) communication technology, which has been proposed for a long time, has become a key technology in the 5G system. [0003] Multiple-input multiple-output (MIMO) technology refers to the simultaneous use of multiple transmit and receive antennas at the transmitter and receiver, so that signals are transmitted and received through multiple antennas at the transmitter and receiver. Therefore, the multiple-input multiple-output technology can realize high-speed, large-capacity data transmi...
