用于5G波束成形的矩形平面与同心圆阵列

Rectangular Planar vs Concentric Circular Array for 5G Beamforming

Md Imrul Hasan, Mohammad Saquib

摘要:

第五代(5G)无线网络中的发射机信号由于使用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。因此,波束成形是5G中重要而强大的工具,可以增强所需方向的信号并抑制来自其他方向的干扰。对于给定数量的天线元件,阵列的几何形状决定其波束方向图。现有文献中的大多数工作都涉及将矩形平面天线(RPA)阵列用于5G波束成形。在这项工作中,我们证明了一个同心圆天线(CCA)阵列是能够产生一个显着更窄的波束比RPA阵列,同时操作与一个显着更少的天线元件在一个相当小的面积。CCA阵列的这种能力可以在链路和系统级别上用于增强5G网络的性能。

英文摘要:

The transmitter 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. Therefore, beamforming is an essential and powerful tool in 5G to enhance signal for the desired direction and suppress interferences from other directions. For a given number of antenna elements, the geometry of the array dictates its beam pattern. Most of the works in the existing literature address the use of rectangular planar antenna (RPA) arrays for 5G beamforming. In this work, we demonstrate that a concentric circular antenna (CCA) array is capable of generating a significantly narrower beam than an RPA array while operating with a notably lesser number of antenna elements on a considerably smaller area. This capability of the CCA array can be exploited and utilized in enhancing the performance of a 5G network in both the link and the system levels.
