Eigenvalue Based Mutual Coupling Reduction
2019 IEEE 89th Vehicular Technology Conference (VTC2019-Spring), 2019This work introduces a novel decoupling technique which employs the theory of coupled characteristic modes for a two element microstrip array. The key idea is to optimize the shape of the decoupling structure using the eigenvalues of the coupled array which can be computed with no prior knowledge of the excitation arrangement.

A Pixelated Resonator for Mutual Coupling Reduction
2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting, 2020In this paper, a systematic procedure to reduce mutual coupling between linear $2 \times 1$ array microstrip antennas is proposed. The proposed design procedure is based on pixelization of the surface between two patch elements and the application of a binary particle swarm optimization (BPSO) algorithm.

Reduction of mutual coupling by near-field coupled resonators
2009 IEEE International Conference on Microwaves, Communications, Antennas and Electronics Systems, 2009A method for reduction of undesirable coupling between two antennas by means of a small resonant element is proposed. The parasitic resonant element is strongly excited by the aggressor antenna radiation and produces a cancellation effect at the victim antenna. This effect is achieved mainly due to the near field of the resonant circuit.

Mutual coupling reduction using coupling matrix based band stop filter
AEU - International Journal of Electronics and Communications, 2020Abstract The capability of the coupling matrix-based band stop filter in mutual coupling reduction between the MIMO arrays is presented. Initially, a microstrip band-stop filter with 3 GHz center frequency is designed using coupling matrix method. This filter structure is then placed between 2×1 radiating patches separated by 0.22 λ in a reference ...
