| Abstract: |
In this study, a single-layer substrate and via-free transmit-reflect-array antenna based on a metasurface is proposed. The array antenna comprises transmissive and reflective unit cells arranged alternately in sequence. To achieve a 360° phase coverage, two sets of antisymmetric U-shaped lines were etched on the top and bottom layers of the substrate to form the transmissive unit cells, and multi-layer stacking and vias are avoided. Moreover, by adjusting the lengths of a split-ring structure with phase delay lines for reflective unit cells, a 360° phase coverage was achieved. The measurement results demonstrated that the antenna simultaneously generates a reflective focused beam with a peak gain of 20.8 dBi and a transmissive +1-mode OAM vortex beam with a peak gain of 20 dBi and a mode purity of 90 % at 17 GHz.
