This paper presents a novel decoupling network which reduces coupling between antennas in multi-antenna systems. Although a lot of studies about decoupling techniques have been presented, this research focuses on the case where the coupling phase between antennas changes rapidly in operation frequency range. The proposed circuit provides the power wave which is same amplitude and opposite phase as the antenna coupling in the frequency range. And antenna coupling is reduced by superposition of them. This paper introduces the behavior of the proposed network and shows design formulas and constraint conditions imposed on the components. The numerical result demonstrates that the network improves isolation between antennas 11dB in Wireless LAN frequency band. |
