Abstract
The design of Rotman lens for ESM sensor application in operation band 32-38 GHz is demonstrated in the paper. Initial design made in Remcom´s Rotman Lens Designer is confronted with the full-wave analysis in CST Microwave Studio as well as with the results of experimental measurements. Rotman lens was tested as a broadband replacement of conventional waveguide reflective phasers intended for the sensor. Parameters of realized prototype are presented and methods of increasing its performance of the structure are outlined.
