| Abstract(in English) | 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 magnitude and phase between antennas changes rapidly in operation frequency range. The proposed network cancels the mutual coupling by the superposition of a designed coupling that has the same magnitude and opposite phase as the original one. This paper introduces the behavior of the proposed network and the design formulas. With the formulas, the resultant coupling with the proposed technique is 26.4 dB smaller than the original one at 12.5% bandwidth although mutual coupling magnitude and phase change 4.9dB and 341°, respectively. |
