Dual-Band and Dual-Polarized Antenna Using Metasurface for 5G Application

A dual-band and dual-polarized antenna using metasurface for 5G application is proposed in this paper. The antenna has achieved excellent dual-band broadside radiation performance maintaining a low profile characteristic by introducing a dual-layer metasurface structure. The bandwidths of the proposed antenna are 13.9% (2.46-2.83GHz) and 14.4% (3.22-3.72GHz), whose overall size is 0.82λ 0 × 0.82λ 0 × 0.053λ 0 . For these dual operating bands, the antenna achieves high realized gains of 8.4-9.88dBi and 9.12-11.85dBi, respectively, with interport isolation over 40dB.
