The design, manufacturing techniques and measurements for wideband Rotman lens are presented. Different design approaches are explained in detail. A step-by-step procedure followed through the design process of a Rotman lens is given. The design equations are derived for both the parallel-plate/waveguide and microstrip/stripline Rotman lens versions. Effects of the design parameters on the lens shape and performance are investigated. A microstrip Rotman lens operating in 8 GHz – 16 GHz frequency band is designed and manufactured. To this end, related theoretical and simulation studies are carried out. The measurement results are compared with the results of the simulation studies.
