Abstract :
A novel planar Rotman lens design for LTCC (Low-Temperature-Cofired-Ceramics) integration is introduced. By folding the lens about the middle plane and utilizing the multilayer features (3D) of LTCC, extremely compact Rotman lenses can be achieved which are attractive for applications in the lower microwave range. Simulation results for the folded and unfolded Rotman lens show very similar results.
