Abstract:
2-D Meta material structure (2DMMS) is proposed to reduce mutual coupling of a two-element micro strip patch antenna. Structure consists of an upper T-shaped patch and two lower U-shaped patches connected with two shorted pins. The proposed 2-D Meta material has a negative permeability at 2.35-2.45 GHz band, which covers the operation band of the patch antenna array with an edge-to-edge array-element distance of 0.13λ0. Meta material is placed on substrate between two antenna elements, which has a 0.1mm vertical distance to the patch antennas. The results show that about more than 18 dB mutual coupling reduction is achieved by using the 2 DMMS without affecting the operating bandwidth and radiation characteristics. Thus, the proposed MIMO antenna with 2-D Meta material achieves an isolation improvement of 20dB in comparison of the simulated MIMO antenna without the proposed Meta material structure.
