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, contro...

| Summary: | 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. |
