Abstract

To minimise the profile of Satcom-on-the-Move ground terminals, in this study, a two-dimensional beam-scanning continuous transverse stub antenna that is based on a compact linear source generator (LSG) is presented. A periodic anti-symmetric two-step (ASTS) structure cascaded with a broadband network is used to construct a single-layer compact LSG. The concept of a parallel-plate waveguide polarisation twister is used to design the ASTS unit that acts as a TE10-to-transverse electromagnetic wave converter, to which chamfers and T-type grooves are added to improve the output plane wave performance over the entire frequency band. A prototype array operating in the band 10.95–12.75 GHz is designed, fabricated, and measured, and the experimental results agree well with the simulated ones. A beam-scanning range of ±61° in elevation is achieved at the central frequency. Although only 29 of 36 slots (ϕ = 0°) contribute to the radiation, the antenna aperture efficiency is still over 60% due to the superior performance of the single-layer minimised LSG.

基于单层紧凑线性源发生器的二维波束扫描连续横向短天线
为了最小化移动卫星地面终端的轮廓,在本研究中,提出了一种基于紧凑型线性源发生器(LSG)的二维波束扫描连续横向短根天线。采用宽带网络级联的周期反对称两步(ast)结构构造了一个单层紧凑LSG。采用平行板波导偏振扭转器的概念设计了作为te10到横向电磁波转换器的ast单元,并在其上添加了倒角和t型凹槽,以改善整个频段内输出平面波的性能。设计、制作并测量了工作在10.95 ~ 12.75 GHz频段的原型阵列,实验结果与仿真结果吻合较好。波束扫描范围±61°的仰角是实现在中心频率。虽然36个槽中只有29个槽(ϕ = 0°)对辐射有贡献,但由于单层最小化LSG的优越性能,天线孔径效率仍然超过60%。
