摘　　要：随着无线通信系统的广泛应用,通信系统不断向着更宽的频段发展,为了改善微带天线带宽窄的缺点,本文设计了一款L形探针馈电的E形宽带微带天线。通过将矩形贴片设计为"E"形结构和运用L形探针耦合馈电代替传统的微带同轴馈电的方法,有效增加了微带天线的阻抗带宽。通过对E形缝隙长度和宽度,L形探针高度和长度参数进行优化,并根据优化结果设计的L形探针馈电的E形微带天线,其-10d B阻抗带宽可达33.3%,达到了展宽微带天线带宽的目的。An E - shaped microstrip antenna with L - probe is presented to expand the bandwidth. The influ-ence of the E - shaped slot and L - probe on the are emphasized. The relationship between them are conclu-ded. Based on the analysis, the result shows that the antenna proposed in this paper has an impedance band-width of 33. 3%.
