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分支共面波导馈电的宽带微带矩形缝隙天线。在保证共面波导特性阻抗始终为100Ω的前提下,通过调整馈电结构中主臂和分支的尺寸以及槽线宽度可以获得较好的匹配。仿真和实验测试表明,该新型宽带微带矩形缝隙天线工作于7.00GHz时,匹配带宽达到了67.60%,电压驻波比小于2。
Based on the conventional construction of microstrip slot antenna, a new wide band rectangle microstrip slot antenna is designed, which is fed by coplanar waveguide （CPW） with fork-like microstrip lines. The impedance of CPW line is 100 Ω. The antenna is matched better through adjusting the dimensions of chief-arm and side-arms and the width of slot lines in feeding net. The results of simulation and test show that 67.60% bandwidth （VSWR〈2） can be obtained at the center frequency of 7.00 GHz.
