Abstract

The present invention relates to a method for reducing antenna coupling by using parasitic resonant structures, a multi-antenna system using the method and a wireless communication device. The methodcomprises a step of arranging a plurality of parasitic resonance structures between a plurality of antennas of the multi-antenna system, and a step of setting the resonance characteristics, number, arrangement positions and resonance frequencies of the parasitic resonance structures as follows to allow the coupling between any two antennas in the multi-antenna system to be reduced: the resonant characteristics of the parasitic resonant structures are set to be consistent with the resonant characteristics of the coupling between multiple antennas, the number of parasitic resonant structures isset to be proportional to a coupling amount which needs to be reduced, the frequencies of the parasitic resonant structures are set to be close to the resonant frequencies of the antennas, and a parasitic resonant structure is set around each antenna of the plurality of antennas and / or between each two antennas of the plurality of antennas.
