MULTI-AERIAL ARRAY OF LONG TERM EVOLUTION MULTI-INPUT MULTI-OUTPUT COMMUNICATION SYSTEM

摘要

Disclosed in an embodiment of the present invention is a multi-aerial array of a long term evolution (LTE) multi-input multi-output (MIMO) communication system, comprising a reflecting board and a feed network arranged on the back of the reflecting board; a plurality of power splitter plates are arranged on the back of the reflecting board for controlling respective power splitting for aerial radiation units of different polarization modes; the plurality of power splitter plates are separately arranged on an upper layer and a lower layer, and are all located in the geometric center of the parallel planes of the reflecting board. The embodiment of the present invention avoids a disordered layout of the feed network of the multi-aerial array of an LTE MIMO communication system, simplifies the feeding mode of aerial radiation units of different polarization modes, reduces the complexity and error rate in the mass production of multi-aerial array of the LTE MIMO communication system, and is easy to troubleshoot or replace a faulty feed circuit.
