摘要

报道了一种由锥形缝隙天线馈电的反射天线的设计与测量。反射射线包含400个由方形斑块和方形环组合而成的单元格。锥形槽天线距离阵列中心90毫米，允许边缘照明水平为-10 dB。在元件设计中考虑了对进给TSA的非球面波前的补偿，从而保证了铅笔束散射波的准确方向。对tsa馈电反射天线进行了样机设计和实验研究。测量到的辐射模式显示出在9.8-10.2 GHz范围内设计的30度增益最大，副瓣电平均低于-10 dB。

Design of A 400-Element Reflectarray Antenna Fed by Tapered Slot Antenna

The design and measurement of a reflectarray antenna fed by a tapered slot antenna (TSA) is reported. The reflectarray contains 400 unit cells combined by square patches and square loops. The tapered slot antenna is 90 mm away from the center of the array, allowing for an edge illumination level of –10 dB. The compensation for the non-spherical wavefront of the feeding TSA is included during the element design, leading to the accurate direction of the scattering wave of a pencil beam. The TSA-fed reflectarray antenna is prototyped and experimentally investigated. The measured radiation patterns show maximum gain at 30 degrees as designed across 9.8–10.2 GHz with sidelobe levels all below –10 dB.
