针对5G/WiMAX/WLAN/X波段MIMO应用，提出了一种超表面基片集成磁电偶极天线。为了提供低轮廓，在不同高度的多层基板中使用与短路壁集成的辐射电偶极子。由于超颖表面和ME偶极子的配合，获得了双宽带和高增益。由于三维六边形结构，MIMO天线系统可以实现良好的包络相关系数和平均有效增益性能。天线元件可以提供66.7%（3.1-6.2 GHz）的阻抗带宽，具有7.6 +/-1.5 dBi的稳定增益，并且对于较低和较高频带，分别提供20.3%（7.1-8.7 GHz）的阻抗带宽，具有7.4 +/-1.8 dBi的增益。元件的整体尺寸为60 x 60 x 7.92 mm（3）。因此，它非常适合未来的5G/WiMAX/WLAN/X波段MIMO通信。
A substrate integrated magneto-electric (ME) dipole antenna with metasurface is proposed for the 5G/WiMAX/WLAN/X-band MIMO applications. In order to provide a low profile, the radiated electric dipoles integrated with shorted wall are used in the multi-layer substrates at different heights. Owing to the coordination of the metasurface and the ME dipole, dual wideband and high gain have been obtained. As a result of the 3-D hexagonal structure, good envelope correlation coefficient and mean effective gain performance can be achieved by the MIMO antenna system. The antenna element can provide an impedance bandwidth of 66.7% (3.1-6.2 GHz) with a stable gain of 7.6 +/- 1.5 dBi and an impedance bandwidth of 20.3% (7.1-8.7 GHz) with a gain of 7.4 +/- 1.8 dBi for the lower and upper bands, respectively. The overall size of the element is 60 x 60 x 7.92 mm(3). Hence, it is well-suited for the future 5G/WiMAX/WLAN/X-band MIMO communications.
