Abstract A general procedure for design and analysis of a Rotman‐type beam‐forming lens using 2‐dimensional field analysis is proposed. Evaluation of reflection coefficients, coupling between ports, main beam direction, 3‐dB beam width and side lobe level are described. The results for a sample case are in agreement with the experimental results. The procedure developed is suitable for CAD implementation leading to optimization of Rotman lens layout configuration.
