Abstract

In this letter, a low-profile wideband pattern-reconfigurable antenna is proposed. The antenna is designed for indoor 5G communication scenarios. The beams can be reconfigured in four tilted directions and one broadside direction. The novelty of this work is that the

${\text{T}}{{{\text{M}}}_{22}}$

and

${\text{T}}{{{\text{M}}}_{20}}$

modes in a metamaterial resonator are tuned together by eight tuning pins, so that a wideband odd-even-mode superposition can be realized, and the antenna can realize wideband tilted beams. The electromagnetic (EM) simulation indicates that the broadside beams have an impedance bandwidth (

${{{\bm{S}}}_{11}}$

< −10 dB) of 3.25 GHz to 3.90 GHz, while the tilted beams have an impedance bandwidth from 3.2 GHz to 4.25 GHz, and in frequency band 3.2 GHz to 4 GHz, a tilted beam about 30° can be observed, the front-to-back ratio in θ = 30° plane is also higher than 7 dB. Finally, a sample antenna is fabricated and tested to verify the simulation.

基于高阶模式的扁平式宽带图案可重构超材料天线

在这封信中，提出了一种低姿态宽带模式可重构天线。该天线专为室内5G通信场景设计。光束可以在四个倾斜方向和一个侧面方向上重新配置。本工作的新颖之处在于将超材料谐振器中的${\text{T}}{{\text{M}}}_{22}}$和${\text{T}}{{\text{M}}}_{20}}$模式通过8个调谐引脚调谐在一起，从而实现宽带奇偶模叠加，天线可以实现宽带倾斜波束。电磁仿真结果表明，侧波束的阻抗带宽（${{{\bm{S}}}_{11}}$<−10 dB）为3.25 GHz ~ 3.90 GHz，斜波束的阻抗带宽为3.2 GHz ~ 4.25 GHz，在3.2 GHz ~ 4 GHz频段，可以观察到约30°的倾斜波束，θ = 30°平面的前后比也高于7 dB。最后，制作了一个天线样品并进行了测试以验证仿真结果。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
