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 $60\times 60\times 7.92$ mm³. Hence, it is well-suited for the future 5G/WiMAX/WLAN/X-band MIMO communications.
