摘要
将射频开关和Koch分形振子天线相结合,设计了一种可工作在多个频段的射频开关加载的Koch振子天线。通过控制射频开关的通断,可使所设计的天线工作在几个不同的频段。所设计的Koch振子天线与普通振子天线相比,其长度有较大幅度的减小。HFSS软件仿真表明所设计的天线在几个不同的频段都具有良好的性能。
This thesis designs a Koch dipole antenna operating in multiple frequency band with radio frequency （RF） switch, by combining Koch fractal dipole antenna with RF switch. The antenna can work at several frequency bands by controlling RF switch. Compared with common dipole antennas,the length of Koch dipole antenna is reduced significantly. The simulation results based on HFSS software indicate that the designed antenna has good performances in several different frequency bands.
