Design of a Hilbert Curve Fractal MIMO Slot Antenna With Enhanced Bandwidth and Stable Radiation Patterns for Wi‐Fi 7 and Wi‐Fi 8 Applications Using Genetic Algorithm

International Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.
Next‐generation Wi‐Fi 7 (IEEE 802.11be) and Wi‐Fi 8 (IEEE 802.11bn) demand compact multielement antennas offering wide bandwidth, high isolation, and stable radiation within limited device space. Conventional MIMO designs often face strong coupling, narrow bandwidth, or low efficiency, restricting high‐throughput multilink performance.
