| Abstract: |
| Sequential rotation feeding(SRF) technology has been widely employed in radio frequency identification(RFID),5G,satellite communication,and millimeter-wave communication systems due to its simplicity of implementation and ability to effectively enhance the bandwidth,gain,and radiation symmetry of circularly polarized(CP) antennas without incurring additional costs.At first,the fundamental principles of designing CP antenna arrays based on SRF technology are introduced,including the selection of radiating elements and the basic types of sequentially rotated feeding networks.Subsequently,with a focus on improving the performance of CP antenna arrays,the techniques for enhancing the performance of radiating elements in SRF technology,key technologies for optimizing feeding networks,and strategies for optimizing the overall performance of CP arrays formed by these two components are reviewed.Finally,the application prospects and development trends of SRF technology in three types of communication systems are summarized,in hope of providing insights and references for the design of CP antenna arrays leveraging SRF technology. |
