PROBLEM TO BE SOLVED: To provide a multi-band multi-antenna system and its communication device.SOLUTION: A multi-band multi-antenna system includes at least one ground plane, two antenna units, a coupling conductor wire, and a grounding conductor wire. The two antenna units each include at least one conductor part, a low-pass filter part, and an extension conductor part. Each antenna unit generates at least one high operation band and low operation band. The low-pass filter part is electrically connected between the conductor part and the extension conductor part, and effectively reduces dependence between the high operation band and low operation band. The coupling conductor wire is placed in the vicinity of the two antenna units, and includes a first coupling part and a second coupling part. The grounding conductor wire is placed between the two antenna units and connected to the ground plane. |
