Dual butler matrix active antenna system

This article describes a smart antenna system that employs low noise amplifiers and two cascaded Butler Matrices. The output signals from the first Butler Matrix, which acts as a beamforming network, have high gain and narrowbeam width for long distance communication while the outputs from the secon...
