摘要
提出了一种微带线一槽线馈电形式的指数锥削缝隙天线，在辐射臂的外边缘引入半椭圆形缝隙来进一步提高天线低频段的定向性，获得了高增益和超宽带性能。利用HFSS12软件进行仿真，天线的极化方式为垂直极化，在2～13GHz的工作频段内电压驻波比〈2，增益最高达11dB，具备良好的定向性，仿真与实测结果基本吻合，表明该设计是有效、可行的。
This paper elaborates a design of the tapered slot antenna. A semi-oval shaped slot is introduced at the outer edge of the radiating arm to improve the directivitry; in the low band, thus achieving an ultra-wide band, wide-beam, high-gain performance. The perpendicular-polarized antenna is simulated and analyzed with HFSS12. The measured results show that the VSWR is less than 2 within 2 -13 GHz, and the highest gain of antenna can be as high as 11 dB with good directionality. The measured results agree well with simulated ones, indicating the effec- tiveness and validity of the design.
