A novel metal ground plane design methodology for optimizing MIMO antenna isolation

Based on the electric platform designs such as All-in-one (AIO) PC, laptop and tablet PC, this article propose a quickly procedure to optimize the isolation of MIMO antennas even though the antenna structure is unknown. With two 50ohm loads as feeding sources, a simplified procedure to optimize the central slotted ground plan was introduced to achieve minimal isolation. Taking a 2.45GHz PIFA antenna system for example, similar trends between real case and simulation were observed, so the feasibility of this proposed method was verified and work well.
