【摘要】 本文设计并分析了一种加载介质引向及透镜结构的超宽带双脊喇叭天线。该天线在双脊喇叭结构的基础上,通过在喇叭段加载介质引向结构,有效提升了天线的驻波性能。进一步地,在介质引向末端加入半球形介质透镜聚焦能量并辐射,实现显著的增益提升和稳定的辐射方向图。基于以上设计,天线在2 GHz至14GHz实现VSWR<2,峰值增益达到15 dBi,天线尺寸仅为84 mm×74 mm×85mm。更多还原

【Abstract】 This paper designs and analyzes an ultra-wideband double-ridged horn antenna loaded with a dielectric director and lens structure.Based on the double-ridged horn configuration,a dielectric guiding structure is introduced in the horn section to effectively improve the antenna’s voltage standing wave ratio(VSWR) performance.Furthermore,a hemispherical dielectric lens is added at the end of the director to focus the radiated energy,resulting in significant gain enhancement and stable radiation patterns.With this design,the antenna achieves a VSWR below 2 across the 2 GHz to 14 GHz frequency range,a peak gain of up to 15 dBi,and a compact size of only 84×74×103 mm.更多还原
