“…The results also verify that adjusting the length of the TTD lines only changed the values of the phase responses and did not influence the resonance characteristics of the unit. Compared with the patch-based unit in [ 21 ], both simulation results of the proposed metasurface-based element and patch-based element [ 21 ] indicate a good agreement of the transmission performance. Moreover, the proposed metasurface-based element had a wider 1-dB insertion loss bandwidth because of the MS and TTD techniques.…”

In this manuscript, a broadband transmitarray antenna (TA) using a metasurface-based element is presented for millimeter-wave communication applications. The metasurface-based TA element adopts a receiver–transmitter configuration: metasurfaces are applied as the receiver and transmitter, and slot-coupled differentially fed striplines are used as the phase compensation. The designed TA element achieves good transmission performance with a more than 360° transmission phase shift range and less than 1-dB transmission insertion loss within a wide frequency range. To verify the proposed TA, a prototype is fabricated based on the conventional printed circuit board (PCB) process, and a pyramid horn is designed as the source. The measured results show that the proposed TA with the differential feed network presents a 1-dB gain bandwidth of 26.2% from 23.5 to 30.5 GHz and a peak gain of 24.5 dBi. The designed TA is a promising alternative for millimeter-wave communications applications because of its high gain, broad bandwidth, low costs, and convenient integration with other circuits.
