一种新型低成本移相技术的研究
Research on novel low cost phase shifting technology
摘要
Abstract
The basic phase shifting unit for the Radant lens is modeled and simulated by use of the commercial simulating software HFSS which is basod 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 10 GHz 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.关键词
