摘要

本文提出了一种应用于Q波段的宽带单层的反射面天线。反射面天线的移相单元由传统的耶路撒冷十字和方形闭环结构组成。基于此双谐振结构,单元相位响应曲线在频带内近似保持平行。经过设计、加工和测试,对拥有576单元的反射面天线进行了验证。测试结果表明,该反射面天线的最大增益为28.2d Bi,最大孔径效率为42.16%,1.5-d B增益带宽为20%(41-50GHz)。
A wideband single-layer reflectarray(RA) antenna is proposed for Q-band application in this paper. The reflectarray phasing element is composed of a conventional Jerusalem cross and a square ring. Based on the dual-resonance structure, its phase response curves are nearly parallel in a wide band, which indicates the wideband performance of the proposed RA antenna. A reflectarray with 576 unit cells has been designed, manufactured and tested for verification. The measured results show that the peak gain is 28.2 d Bi and the peak aperture efficiency is 42.16%. Besides, the 1.5-d B bandwidth is 20%(41-50 GHz).
