Abstract
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 3D hexagonal structure, good ECC and MEG performance can be achieved by the MIMO antenna system. The antenna element can provide an impedance bandwidth of 66.7% (3.1 GHz-6.2 GHz) with a stable gain of 7.6±1.5 dBi, and an impedance bandwidth of 20.3% (7.1 GHz-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 60×60×7.92 mm3. Hence, it is well-suited for the future 5G/WiMAX/WLAN/XBand MIMO communications.
