This repository contains a research-grade MATLAB/Simulink implementation of a 32-by-32 Butler Matrix (BM) beamforming network (BFN) developed as a large-scale theoretical software demonstrator. The ...

This passive beamforming topology is not well known but is widely used — a common situation in the RF world. For many years, radar applications defined much of the world of directional antennas. These ...

Abstract: In this paper, a beam-switching multibeam antenna with wide bandwidth and compact size is investigated for Vehicle-to-Everything (V2X) applications. An extended 4 × 4 Butler matrix topology ...

Abstract: This paper proposes a dual-mode Butler matrix based on the air suspended line (ASL) for millimeter-wave (mm-wave) dual-polarized antenna arrays. The ASL, which can simultaneously support TEM ...
