上海65m射电望远镜Ka波段极化器设计

THE DESIGN OF SH65 RADIO TELESCOPE Ka BAND POLARIZER

该文比较详细地论述了上海65m射电望远镜上Ka波段(30～34GHz)宽带极化器的设计。重点介绍了宽带差分移相器和宽带正交模转换器的设计和HFFS仿真,并给出了两者组合后的仿真结果。整个极化器符合65mKa波段极化器所要求的总体设计指标。文中首先谈到了设计Ka波段极化器的背景,论及了当前国内外在这一领域的发展近况,然后就65m射电望远镜Ka波段极化器设计做了深入的展开,并给出了相应结论。

The design of the SH65 radio telescope Ka band polarizer is described in detail in this paper. The important points are the design and HFFS simulation of Differential Phase Shifter and Orthomode Transducer,and the results obtained from the combination of the two parts are given. The polarizer satisfies the demand of the SH65. After the background is mentioned,the detail design and discussion of the polarizer are addressed. And the results of the simulations are given as well.
