Miniaturize Dual‐Band Open‐Loop Resonator‐Based MIMO Antenna With Wide Bandwidth and High Gain

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2024, Issue 1, 2024.
This paper proposes and analyzes a 2 × 2 multi‐input multioutput antenna based on an open‐loop resonator structure and an inverted L structure. The top layer of the antenna uses symmetric inverted hook‐shaped and inverted L branches and is connected to the bottom layer of the dual‐feed port and the ground plane using the VIAs, respectively.
