A two-dimensional Rotman-lens feeding circuit was designed for planar two-dimensional multi-beam antenna using multi-layer substrate integrated waveguide in the millimeter-wave band. Metal patterns between the substrates are partly etched to form Rotman-lens in the E-plane as well as in the H-plane. A complete two-dimensional multi-beam forming circuit is integrated in the multi-layer substrate. The beam-forming performance was evaluated by array factors from the simulated S-parameters of the two-dimensional multi-beam forming circuit in this work.
