Monolithic fabrication of Rotman lenses

©2003 COPYRIGHT SPIE--The International Society for Optical EngineeringRotman lenses have the potential to solve many problems associated with high frequency antenna arrays. Offering compact, rugged and reliable means of forming muli-beam, staring array sensing arrangements, these lenses may prove very useful if robust solutions to some important problems are to be found. This paper presents the performance of a Rotman lens design and discusses the challenges associated with the design of these lenses.Leonard T. Hall, Hedley J. Hansen, and Derek Abbot
