A Novel Design of Miniaturized Butler Matrix

In this paper, we design a stepped miniaturized 4 × 4 Butler matrix using the principle of impedance transformation. Compared with the traditional Butler matrix, the miniaturized Butler matrix has a reduced area of 78.6%, and the output amplitude is stable, the output phase gradient meets the design requirements.
