The one-body 2-D Beam-switching Butler Matrix and the 2-D Beam-switching Rotman Lens are compared. Those are designed to have sixteen 2-D arranged beams. Comparing the proposed Butler matrix with the Rotman lens, it has the low transmission loss, the high uniformity of distributed beams, and the small size. However when the number of 2-D arranged beams is increased, the size of the Butler matrix is larger than the size of the Rotman lens. © 2016 IEICE.
