Enhanced functionality of a microwave Rotman lens using a retrodirective architecture and liquid crystal phase shifters

open access: yes, 2013
The Rotman lens is a beam former which is attractive due to its wide bandwidth, wide angular cove rage, planar nature and simple fabrication. Its angular resolution is limited because only a discrete number of steering angles (equal to the number of ...

Wide-angle Scanned Microstrip Rotman Lens Design in X Band

open access: yes
In this study, a Rotman lens design with 7 beam ports and 17 array ports capable of simultaneously or sequentially steering the array antenna beam in 7 different scanning angles within an 82-degree angle range has been developed.
