In this paper, a new design of compact Multi Input and Multi Output (MIMO) elliptic ring antenna applied to 5G-UWB wireless mobile communications is discussed. There are two designs, first design consists of two radiators both are perpendicular in single side. The second design consists of four radiators and they are perpendicular to each other in single side. Those designs are compact with small size of substrate material Roger 4003 mounted over partial ground with dimensions of 30 × 30 × 0.203 mm³ for four antenna radiators and 15 × 30 × 0.203 mm³ for two antenna radiators. The operating frequency of the proposed designs which support MIMO microstrip patch antennas is 60 GHz for Milli-Meter short wave range applied for 5G Ultra-Wide Band (UWB) applications. The simulated results are validated by testing the fabricated antenna model and a good consistency is observed in terms of impedance and radiation characteristics. The diversity performance is also tested and good results are obtained in terms of ECC and DG.

本文讨论了一种应用于 5G-UWB 无线移动通信的紧凑型多输入多输出 (MIMO) 椭圆环形天线的新设计。有两种设计，第一种设计包括两个在单侧垂直的散热器。第二种设计由四个散热器组成，它们在单侧相互垂直。这些设计紧凑，基板材料尺寸小 Roger 4003 安装在部分地面上，尺寸为 30 × 30 × 0.203 mm ³用于四个天线辐射器和 15 × 30 × 0.203 mm ³用于两个天线辐射器。对于应用于 5G 超宽带 (UWB) 应用的毫米短波范围，支持 MIMO 微带贴片天线的建议设计的工作频率为 60 GHz。通过测试制造的天线模型验证了模拟结果，并在阻抗和辐射特性方面观察到了良好的一致性。对分集性能也进行了测试，在 ECC 和 DG 方面获得了良好的结果。
