摘要： Various examples are provided for point symmetric complementary meander line (PSC-ML) slots, which can be used for mutual coupling reduction. In one example, an antenna array includes first and second patch antenna elements disposed on a first side of a substrate, the first and second patch antenna elements separated by a gap. The antenna array can include point symmetric complementary meander line (PSC-ML) slots formed in a ground plane disposed on a second side of the substrate. The PSC-ML slots can include a pair of ML slots aligned with the gap between the first and second patch antenna elements. In another example, a method includes forming first and second antenna elements on a first side of a substrate and forming PSC-ML slots in a ground plane disposed on a second side of the substrate that are aligned with a gap between the first and second antenna elements.
