Rotman Lens Design And Simulation In Software

Source: Remcom, Inc.

Since its invention in the early 1960s, the Rotman Lens has proven itself to be a useful beamformer for designers of electronically scanned arrays. Inherent in its design is a true time delay phase shift capability that is independent of frequency and removes the need for costly phase shifters to steer a beam over wide angles. This article uses the developed software to design and analyze a microstrip Rotman Lens for the Ku band. Download the article for more information.
