摘要

本文提出了一种低旁瓣全息调制电抗表面天线。通过合理控制天线孔径分布，可以实现低旁瓣。通过微小改变全息天线单元格上的贴片，实现了天线孔径场和低旁瓣的余弦分布。并比较了不同调制因子对旁瓣电平的影响。设计的天线工作频率为10 GHz，辐射角为30°，仿真增益为17.1 dBi，旁瓣电平为l0.4dB。

Low Sidelobe Holographically Modulated Reactance Surface Antenna

A low sidelobe holographically modulated reactance surface antenna is proposed in this paper. The low sidelobe can be achieved through properly controlling of the antenna aperture distribution. By slightly changing of the patch on unit cell of holographic antenna, the cosine distribution of antenna aperture field and the low sidelobe is realized. And the effect on sidelobe level with different modulation factor is also compared. The designed antenna works at 10 GHz with radiation angle of 30 deg, and the simulated gain reaches 17.1 dBi with sidelobe level of l0.4dB.
