- W3147142322 abstract "The current study aimed to introduce a novel type of dual-layer polarization insensitive transmitarray antenna operating at 76.5 GHz. The dual-layer unit-cell consisted of two coplanar patches printed on one substrate. In this paper, a total of eight unit-cell structures were designed, with a step size of 45 degrees, and a transmission magnitude greater than −1dB at 76-77 GHz. These eight unit-cells were arranged on a 50*50-element transmitarray for achieving a 3-bit phase quantization. Our simulation results indicated that the antenna achieved a maximum gain of 32.4 dB with a aperture efficiency of 22%, a −1 dB bandwidth of 9.15% and a side lobe level of less than −20 dB. This dual-layer coplanar structure markedly reduced the complexity and manufacturing difficulty of the transmitarray, especially at the millimeter-wave frequencies." @default.
