Design and development of adaptive phase shifting module for antenna beam self-alignment

The target of this project is to establish an automatic system about phase array which can detect and control phase difference so that keep antenna unchanged. Therefore, there is a negative feedback loop system constructed which use antenna, phase shifter, directional coupler, phase detector, controller, comparator and low-pass filter.Phased array antenna is an important role in wireless communication system and composed of many radiating elements each with a phase shifter. In this project, the phased array antenna system will drive a phase shifter. And the prototype of negative feedback loop system will be tested as well as some the properties of components. And some components manufactures were learned and practiced.Bachelor of Engineerin
