This article presents the electromagnetic (EM) wave routing technique using single-epsilon-high (single-EH) anisotropic medium to generate dual-beam radiation at 28 GHz band for next generation communication systems. This technique is implemented using SIW dipole antenna loaded with the single-EH anisotropic medium realized using modified asymmetric electric-LC (ELC) metamaterial unit cell loaded vertically in front of the radiator. The technique is first verified using simulations and then practically realized, and the results are in good agreement with the predicted theoretical results. The effect of the thickness of the media loading the antenna is investigated and dual-beam radiation in the frequency band 26–31 GHz is obtained by choosing the appropriate number of ELC-slabs. The measured results confirm 26–31 GHz impedance bandwidth and dual-beam radiation directed along 50° and 130° with 8 dBi beam peaks.

使用单 Epsilon 高各向异性介质在 28 GHz 下路由电磁波的双波束天线

本文介绍了电磁 (EM) 波路由技术，该技术使用单 epsilon-high（单 EH）各向异性介质在 28 GHz 频段为下一代通信系统生成双波束辐射。该技术是使用加载有单 EH 各向异性介质的 SIW 偶极子天线实现的，该介质使用改进的非对称电 LC (ELC) 超材料单元在辐射器前面垂直加载。该技术首先通过模拟验证，然后实际实现，结果与预测的理论结果非常吻合。研究了加载天线的介质厚度的影响，并通过选择适当数量的 ELC 板来获得 26-31 GHz 频段内的双波束辐射。
