2024 18th European Conference on Antennas and Propagation (EuCAP)(2024)
摘要
In this work, a two-port Multiple Input Multiple Output (MIMO) antenna with a metamaterial surface for mm-Wave 5G MIMO Applications is proposed. The two-port MIMO antenna has a compact size of 10 × 20 × 0.78 mm

and is realized using Rogers Duroid 5880 substrate with a thickness of 0.78 mm. Each one of the two radiation elements is composed of a square cut- at- the-corners, patch antenna. In addition, three metasurface array structures of 8 × 2 metacells are used at the same level with the radiation elements and as a result the impedance bandwidth and the isolation are improved significantly. The performance of the antenna is investigated in terms of reflection coefficient, isolation, impedance bandwidth, radiation characteristics, and MIMO parameters such as Envelope Correlation Coefficient (ECC) and Diversity Gain (DG). The proposed two-port metamaterial antenna achieves impedance bandwidth of 3.37 GHz (25.41-28.48 GHz) or 12.48%, an overall Peak Realized Gain of 10.02 dB and isolation between antenna elements is larger than 20 dB. Additionally, the calculated MIMO performance parameters confirm satisfactory behavior οf the proposed antenna.
