This brief presents a dual-band dual polarization (DP) antenna based on a cross-shaped
metasurface with a terminal double-loop structure (TDLS) applied to 4G/5G base stations.
The Fabry-Perot (FP) cavity is formed by introducing the TDLS metasurface above the dipole
radiators, realizing the transition from single-band to dual-band and increasing the gain.
After loading the TDLS metasurface, the DP antenna, whose total height is and planar
reflector at the bottom is (where is the wavelength at resonance point 2.3 GHz), realizes two …

This brief presents a dual-band dual polarization (DP) antenna based on a cross-shaped metasurface with a terminal double-loop structure (TDLS) applied to 4G/5G base stations. The Fabry-Perot (FP) cavity is formed by introducing the TDLS metasurface above the dipole radiators, realizing the transition from single-band to dual-band and increasing the gain. After loading the TDLS metasurface, the DP antenna, whose total height is and planar reflector at the bottom is (where is the wavelength at resonance point 2.3 GHz), realizes two broad bands of 2.05-2.55 GHz (21.74%) and 3.09-3.71 GHz (18.24%), reaching average gains of 8.86 dBi and 7.40 dBi respectively, which is about 3 dBi higher than that without metasurface, and has a stable radiation pattern. As well as, the 3-dB half-power beamwidth (HPBW) is stabilized at , and the isolation is more splendid than 30 dB. Eventually, the radiation efficiency stabilized at around 85%.
