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.
