Isolation-enhanced dual band MIMO antenna with defective ground structure and stubs as a hybrid decoupling structure for next-generation sub-6 GHz uses

Key Points

• Improved isolation in the dual band MIMO antenna enhances overall performance, especially at sub-6 GHz frequencies.
• Key evidence shows increased decoupling efficiency, with measurement results illustrating significant improvements over standard designs.
• Analysis of the antenna's design reveals the effectiveness of the defective ground structure and stubs as hybrid decoupling elements.
• Potential applications may enable better performance in next-generation wireless communication systems, necessitating further testing.
