Frequency-Dependency Characteristic of a 4x4 Butler Matrix for 5G sub-6 GHz application

Butler matrix (BM) is a widely used beamforming technique in array signal processing that enables efficient and precise signal distribution to multiple antenna elements. However, the frequency-dependent nature of their design restricts the effectiveness of the conventional Butler matrix to a specifi...
