| Summary: | 碩士 === 元智大學 === 通訊工程學系 === 101 === The research intend to design a phase array antenna with reconfigurable beams by a kind of modularize phase shifter.
The Modularize phase shifter can be input in four bits and output in sixteen levels with 360 degrees phase coverage. Base on above characteristic of phase shifter, which design a specific digital controller by microcontroller to control phase shifters. Besides place the phase shifter after three levels of Wilkinson power divider and also made 2*4 planar array antenna with specific space between antenna units; then intergrade array antenna and power divider with coaxial cables. Because of it, the purpose can be attached to arrange reconfigurable beams with main beam which has 10 degrees shift in every 45 degrees phase difference.
