摘要：
This paper presents a triple-mode dual-polarized metasurface antenna with high isolation for fifth-generation (5G) terminal applications. The proposed antenna consists of a 4 x 4 nonuniform metasurface radiator and a cross-shaped feeding probe. Based on the theory of characteristic modes (TCM), the resonance potential of the different characteristic modes (CMs) is discussed for the proposed nonuniform metasurface radiator. By combining the differential-fed scheme, three pairs of degenerate modes can be excited to realize wide impedance bandwidth. Meanwhile, the independent tuning characteristics for the three resonances are also achieved. The simulated results show the proposed dual-polarized antenna with a low profile of 1.8 mm can cover 3.3-4.2 GHz with 45 dB isolation, which is promising to be applied to the dielectric back cover of 5G mobile devices.
