Design of new optical butler matrix beamforming network for phased array antenna

Abstract EN

The recent dramatic advances in high-speed photonic components have opened up significant applications of hybrid light-wave, microwave and millimeter wave systems.

This paper explores the use of the interface between photonics and microwave and millimeter wave for designing efficient beamforming networks for phased array antennas.

A single-beam optical beamforming system is proposed and analyzed.

The system is studied and their result is presented at two different levels: the first one is the system architecture and the second is the optical control devices for controlling the beamforming networks.

The proposed system use Butler matrix scheme to achieve beamforming.

Mathematical analysis is presented to clarify the operation of the proposed system.

Some results are presented to assess the performance of the proposed scheme.
