摘要
本文提出了一种圆极化频率可重构天线。该天线包括一个带有四个C型缝隙和中间开槽的圆形贴片。可以发现,该天线的工作频率(1600MHz和2793MHz)主要由圆形贴片和C型缝隙控制,而圆极化则是由中间开槽实现的。此外,该天线还具有低剖面、尺寸小(半径为22mm)等优点。本文利用HFSS软件对设计进行仿真分析,仿真结果表明该天线性能良好。
A novel circularly-polarized frequency reconfigurable antenna is proposed in this paper？ The antenna includes a circular patch with four C-shaped slots and a narrow slot in the center？ It is observed that the lower（1600 MHz） and upper（2793 MHz） resonance frequencies are controlled by the circular patch and the C-shaped slots？ The CP operation is mainly achieved by the narrow slot？The antenna has a low profile and a small size with a radius of 22 mm？ An electromagnetic model of the designed antenna is developed in HFSS for analysis and optimization,the simulation results show that the antenna has good impedance matching characteristics？
