摘要

本文提出了一种新型宽带纯金属反射天线。设计的工作频率为12.5 GHz的反射天线采用改进的缝隙结构，不含介质衬底。槽型元件经过优化，可提供线性相位曲线，并实现超过360度的相移范围。采用偏置馈电结构，设计并仿真了9×9单元反射天线。仿真结果表明，在13.1 GHz时最大增益为19.9 dB，增益带宽为13.6%，为1 dB。

Design of A broadband metal-only reflectarray antenna with modified slot-type elements

This paper presents a new broadband metal-only reflectarray antenna. The designed reflectarray antenna operating at 12.5 GHz doesn't contain any dielectric substrate by using a modified slot structure. The slot-type element is optimized to provide a linear phase curve and a phase-shift range in excess of 360 degrees is achieved. With an offset feed configuration, a 9×9 elements reflectarray antenna is designed and simulated. The simulation results show a maximum gain of 19.9 dB at 13.1 GHz with 13.6%, 1-dB gain bandwidth.
