Rotman lens used as a demultiplexer/multiplexer

open access: yes2012 42nd European Microwave Conference, 2012
A new type of microwave demultiplexer is proposed which combines an arrayed waveguide grating (AWG) and a Rotman lens. The dispersion property of an AWG is employed to produce different phase slope responses for different frequencies, while the Rotman lens routes the frequency components onto different ports.

Fourier Transform using a Rotman Lens

open access: yes2012 42nd European Microwave Conference, 2012
In this paper, the design constraints that are required for a Rotman lens to realize discrete Fourier transform (DFT) amplitude and phase functionality are derived. A Fourier Rotman lens has been designed, fabricated and validated. The amplitude and phase response and the array pattern based on the CSTTM results are validated with the theoretical DFT ...
