Abstract :
A microstrip Rotman lens for Ku band was simulated to validate the accuracy of the FDTD method for these devices as a first step in the development of a full-featured design tool. The simulated results from the lens were compared with measurements of phase and amplitude taper across the output ports, and for broad band S parameters.
