Abstract

Reconfigurable antenna technology is a hot topic in the field of antenna. The reconfigurable antenna can realize the functions of multiple antennas on only one antenna. In this paper, a circularly polarized reconfigurable antenna, which is one of the reconfigurable antennas, is explored. After briefly introducing the concept and characteristics of circularly polarized reconfigurable antenna, the impedance bandwidth, axial ratio and polarization direction of a circularly polarized reconfigurable antenna are analysed. Based on summarizing the research results of polarized reconfigurable antennas in recent years, the structure diagram of circularly polarized reconfigurable antennas is drawn. Subsequently, HFSS software is used to simulate the polarization reconfigurable antenna, focusing on the parameters such as standing wave, axial ratio and polarization direction. Simulation results show that the proposed method can effectively improve the antenna bandwidth without increasing the antenna volume significantly.
