DEVELOPMENT OF A BROADBAND 4x4 BUTLER MATRIX DESIGNED FOR BEAMFORMING NETWORK
Wireless power transmission (WPT) has emerged as a compelling energy alternative set to extend its capabilities, enabling the wireless delivery of electricity to a micro unmanned aerial vehicle (UAV). We propose the utilization of a contemporary circular polarized micro strip antenna (CPMA) configuration for the 5.8 GHz retina system. This paper investigates the low-cost beam forming network approach for antennas array applications at frequency 5.8 GHz. As a result, a reconfigurable planar antenna and a 4×4 Butler matrix are developed. The simulation analysis is performed by CST Microwave Studio and compared with ADS software. The beamforming network has an overall size of 84.74 mm * 76.56 mm. Furthermore, it exhibits a return loss of under -10 db. The Butler matrix demonstrates superior insertion loss characteristics, along with minimized phase shift deviations among its output ports. A prototype of the beamforming network has been successfully developed. Simulation results together with further comparisons will be presented in the paper. The Butler matrix features a lower insertion loss and a lower phase shift deviation. In the interconnection among the output ports. A beamforming network prototype has been implemented. The publication will give the simulation findings as well as other comparisons.
