摘要

本文介绍了一种新型的磁电偶极子天线，该天线具有低交叉极化电平和高前后比(FBR)的特点，可用于第5代(5G)室内通信。通过将常规贴片分成两对矩形贴片和四对寄生贴片，可以抵消产生交叉极化的电流。此外，垂直栅栏可以有效地扩大天线的波束宽度。实验结果表明，5G通信可实现3.3-4.2 GHz(24%)的宽带带宽。此外，在工作频段内，交叉极化电平低于- 20 dB, FBR电平约为26 dB。e面和h面均可获得100°的宽波束宽度。

A Wide-Beamwidth Magneto-Electric Dipole Antenna with Low Cross-Polarization and High Front-to-Back Ratio

A novel magneto-electric (ME) dipole antenna is presented in this paper, which owns the characteristics of low cross polarization level and high front-to-back ratio (FBR) for the Sth-generation (5G) indoor communications is described. By dividing the conventional patches into two pairs of rectangle patches and four pieces of parasitic patches, the current which produces cross-polarization can be offset. Furthermore, the vertical fence can effectively widen the beamwidth of antenna. Experiment results demonstrate that a broad frequency bandwidth of 3.3-4.2 GHz (24%) can be achieved for 5G communications. Besides, a cross - polarization level below −20 dB and a FBR level of approximately 26 dB in the operating bands. Noting that a wide beamwidth of 100° for E-plane and H-plane is also obtained.
