Real-world rotman lens prototyping and analysis

In this paper, tools to semi-automate and speed up the Rotman lens design process are suggested, allowing researchers to rapidly iterate designs or produce studies that span multiple design parameters. As guidance for the analysis of these lenses, methods for measuring or simulating insertion loss and beam efficiency of the entire lens are described. These are real-world characteristics that must be assessed and optimized if Rotman lenses are to contend with other phase-shifting devices for military or commercial use.
