Abstract
In this paper, a polarization-independent chain Huygens’ metasurface is proposed. It is polarization multiplexing of two chain structures. Owing to the polarization-independent property, it can be conveniently applied to design double-layer dual-polarized transmitarray antennas (TAAs) with low profile. The measured results show that, for the designed low-profile dual-polarized TAA, its peak gain is 29.7 dBi at 28 GHz with aperture efficiency of 48.9 %, and the 3-dB gain bandwidths is 8.8 %. With the F/D ratio of only 0.36, the proposed low-profile dual-polarized TAA based on the chain Huygens’ metasurface has critical applications in antenna engineering.
