大孔径UCCA阵列在5G用户密集网络中的性能
Performance of Large Aperture UCCA Arrays in a 5G User Dense Network
摘要：
第五代（5G）无线网络中的传输信号由于使用Sub-6 GHz和毫米波（mmWave）频带中的较高频率而遭受显著的路径损耗。超密集网络中的用户间干扰对提供高数据率提出了额外的挑战。因此，期望生成窄波束以通过增加天线增益来扩展5G网络的覆盖范围，并通过减少用户间干扰来提高其容量。这一事实促使我们在大规模多输入多输出（MIMO）技术中使用大口径均匀同心圆天线（UCCA）阵列进行5G波束成形。我们的分析表明，具有较大天线元件间距的UCCA能够产生比矩形平面天线（RPA）阵列更窄的波束，具有中等的旁瓣电平，同时使用相同数量的天线元件进行操作。分析UCCA的这种能力，以发现5G网络的性能增益。
英文摘要：
The transmitted signals in the fifth generation (5G) wireless networks suffer from significant path loss due to the use of higher frequencies in Sub-6 GHz and millimeter-wave (mmWave) bands. Inter-user interference in an ultra-dense network offers additional challenges to provide a high data rate. Therefore, it is desirable to generate narrow beams to extend the coverage of a 5G network by increasing antenna gain and improve its capacity by reducing the inter-user interference. This fact leads us to address the use of large aperture uniform concentric circular antenna (UCCA) arrays for 5G beamforming in massive multiple-input-multiple-output (MIMO) technology. Our analysis demonstrates that a UCCA with a larger antenna element spacing is capable of generating a significantly narrower beam with a moderate side-lobe level than a rectangular planar antenna (RPA) array while operating with the same number of antenna elements. This capability of the UCCA is analyzed to discover the performance gain of a 5G network.
