摘要：

运用基于有限元法的商业软件HFSS对Radant透镜的基本单元进行了建模和仿真计算，获得了影响基本相移单元插入相移的主要结构参数．在此基础上，设计了两种满足工程研制需要的新型基本相移单元．仿真表明，这两种新型单元在以10GHz为中心频点的8%的工作带宽内，相位不平衡度小于6°，并具有良好的传输特性．最后，通过组合这两种新型单元，设计了一种相移位数为5位的结构新颖的Radant透镜式移相器，其电扫描精度比传统的4位数字式Radant透镜式移相器要高．

关键词: Radant透镜, 移相器, 基本相移单元, 插入相移

Abstract:

The basic phase shifting unit for the Radant lens is modeled and simulated by use of the commercial simulating software HFSS which is based upon FEM and the main structural parameters that influence the inserting phase shifting are obtained. Based on the above work, two novel basic phase shifting units that meet the requirements in the engineering are devised, and simulated results demonstrat that these two novel units achieve phase imbalance of less than 60 and good transmission characteristics in the 8% operating frequency band with 10GHz as the center frequency. Finally, a new Radant lens phase shifter with a 5-bit digital phase setting is designed by a combination of these new units, which shows a more precise 2D scanning capability in comparison with the traditional 4-bit digital Radant lens phase shifter.

Key words: Radant lens, phase shifter, basic phase shifting unit, inserting phase shifting
