Numerical and experimental generated data during project https://doi.org/10.1109/ACCESS.2025.3549619

The dataset was generated during a project aimed at developing a novel design methodology for multiple-input multiple-output (MIMO) microstrip patch antenna (MPA) arrays utilizing mode diversity. Typically, similar modes are excited in each element of the MIMO array. However, the proposed MIMO array uses two elements of different sizes excited in distinct modes at the same frequency. It is found that the TM01 mode excited in one MPA, a hybrid mode (TM03 + TM21) is induced in the coupled MPA, while exciting the TM03 mode in another patch induces a quasi-TM11 mode in the coupled MPA. Both induced modes exhibit weak fields at the feeding points, reducing the mutual coupling between the two patch antennas without requiring extra decoupling structure.
