摘要
提出了一种新型高增益宽频天线结构,采用低介电介质,在高于贴片1mm,间距2.5mm处加载3个宽1.5mm的方环形金属片。利用HFSS仿真软件对该天线进行仿真,最大增益达到了19.466dB,比未加载时增加10.14dB,相对带宽增加了1.37%,且全向性好,体积小,结构简单,成本低。
A new structure with high gain and wide band antenna was developed. This antenna uses the low coefficient of dielectrical loss medium, loading three square link tinsel which is higher than pastes the piece tolmm,the distance between two neighboring wide square shape link tinsel is2. 5mm. The antenna was simulated by HFSS, and its biggest gain achieves to19. 466dB. Compared with the antenna without loading, the gain increases by 10. 14dB and the bandwidth increases by 1.37%. The new antenna has good full orientation, small volume, simple structure and low cost.
