摘要
在传统结构微带缝隙天线的基础上,设计了一种采用叉状馈电结构的宽带微带圆形缝隙天线。通过调整馈电结构中主、侧臂的尺寸可以获得较好的匹配。经过仿真和实验测试,该结构的宽缝天线工作于2 GHz时,匹配带宽达到了32.5%(VSWR<1.5)。
Based on the conventional construction of microstrip slot antenna, a new wide band microstrip circle - slot antenna is designed, which is fed by a fork - like microstrip line. Better matches can be achieved through adjusting the dimensions of chief - arm and side - arms in feeding net. The results of simulation and test show that 32.5% bandwidth （ VSWR 〈 1.5） can be obtained at the center frequency of 2 GHz.
