Summary:
In this paper, we propose a novel decoupling method for compact multiple antennas. Three neighboring antennas are used for two port system and the two ports are decoupled on the array antenna. The orthogonality of two ports is achieved by giving orthogonal excitation weight to three antennas, where the weight is determined by SVD (Singular Value Decomposition) of the MISO (Multiple-Input Single-Output) channel. This paper also demonstrates the basic characteristics and improvement on radiation efficiency by the proposed method via the analysis using moment of method (MoM).
