中文摘要：
为了提升微带天线的带宽,设计了一种具有U型调谐枝节的宽频带E型微带天线。通过在传统的E型微带天线引入U型调谐枝节,改变电容电感,优化天线的阻抗匹配,使得带宽增加了16.7%。仿真结果表明,该天线实现了26.1%的相对带宽,工作频率范围为2.0~2.6 GHz（S11〈-10 d B）。
英文摘要：
A wideband E-shaped microstrip antenna with U-shaped tuning stub is designed for improving bandwidth of the microstrip antenna. The impendence matching is optimized through introducing the U-shaped tuning stub which changes the capacitance and inductance of the designed antenna. The modified E-shaped microstrip antenna achieves 16.7 % wider bandwidth than the conventional antenna, which has a 26.1% impendence bandwidth arranged from 2 GHz to 2.6 GHz （S11 〈- 10 dB）.
