摘要:

在叙述圆柱形介质谐振器及其频率特性的基础上,通过基于有限元法的高频结构仿真软件Ansoft HFSS 12仿真,获得圆柱形介质谐振器半径与高度变化对天线工作带宽和增益的影响,得到驻波关系曲线图。通过分析仿真结果,得出在Rc=2.9 mm,Hc=4 mm时天线性能最佳,优化的圆柱形介质谐振器的参数有利于提高天线的性能。

关键词: 圆柱形介质谐振器, 电磁仿真, 驻波比

Abstract:

Based on the theory of the DRA and antenna feed mode,the thesis analyzes the influence of two factors on the antenna performance including the height and radius of the cylindrical dielectric resonators.Ansoft HFSS is applied to establish this model and the simulated VSWR is offered as a result.The simulation results show that the antenna performance is the best when Rc is 2.9 mm and Hc is 4 mm,and that the optimized parameters of the cylindrical dielectric resonator improve the performance of the antenna.

Key words: cylindrical dielectric resonator;electromagnetic emulation;VSWR
