摘要:

八元素,紧凑型超宽带-多输入多输出UWB-MIMO(超宽带多输入多输出)天线能够为未来的第五代(5G)终端设备提供高数据速率,同时为第三代(3G)和第四代(4G)通信提供必要的带宽,其通过部署电感电容器(LC)来实现从4.85到6.35 GHz的带阻提出了在接地平面上的短截线。集成的短截线还提供了灵活性,以拒绝任何选定的频带以及带宽控制。印刷单极子的正交放置允许偏振多样性并提供高隔离。在所提出的八元件UWB-MIMO/分集天线中,天线对3-4是位于平面50 X 50 mm 2基板的相对角上的天线对1-2的180 °镜像变换。然后将四个额外的单极子垂直放置在同一板上,导致总尺寸仅为50 x 50 x 25 mm 3。仿真结果进行了验证,通过比较制造的原型的测量。得出的结论是,该设计满足目标规格在整个带宽的2至12 GHz的反射系数优于-10 dB(拒绝带除外),隔离度超过17 dB,低包络相关性,低增益变化,稳定的辐射模式,并在无线局域网(WLAN)频带的信号强抑制。总体而言,所提出的八元件架构的紧凑和降低的复杂性,增强了其在文献中存在的其他MIMO天线设计中用于未来5G终端设备中的分集应用的实际可行性。

英文摘要:

An eight element, compact Ultra Wideband-Multiple Input Multiple Output (UWB-MIMO) antenna capable of providing high data rates for future Fifth Generation (5G) terminal equipments along with the provision of necessary bandwidth for Third Generation (3G) and Fourth Generation (4G) communications that accomplishes band rejection from 4.85 to 6.35 GHz by deploying a Inductor Capacitor (LC) stub on the ground plane is presented. The incorporated stub also provides flexibility to reject any selected band as well as bandwidth control. The orthogonal placement of the printed monopoles permits polarization diversity and provides high isolation. In the proposed eight element UWB-MIMO/diversity antenna, monopole pair 3-4 are 180o mirrored transform of monopole pair 1-2 which lie on the opposite corners of a planar 50 x 50 mm2 substrate. Four additional monopoles are then placed perpendicularly to the same board leading to a total size of 50 x 50 x 25 mm3 only. The simulated results are validated by comparing the measurements of a fabricated prototype. It was concluded that the design meets the target specifications over the entire bandwidth of 2 to 12 GHz with a reflection coefficient better than -10 dB (except the rejected band), isolation more than 17 dB, low envelope correlation, low gain variation, stable radiation pattern, and strong rejection of the signals in the Wireless Local Area Network (WLAN) band. Overall, compact and reduced complexity of the proposed eight element architecture, strengthens its practical viability for the diversity applications in future 5G terminal equipments amongst other MIMO antennas designs present in the literature.
