Enhanced functionality of a microwave Rotman lens using a retrodirective architecture and liquid crystal phase shifters
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 input ports) can be achieved. This limitation is o...
