【摘要】 本文提出了一种基于锥形天线的宽带垂直极化全向天线。通过对锥体的顶端加载、短路支节加载、介质加载以及集总元件加载,改变天线结构中电流路径,使天线的等效尺寸大大增加,同时实现了小型化和宽带匹配。基于此种加载的盘锥天线,能够实现三倍频的宽带匹配(VSWR<2.5),天线的横向电尺寸为0.633个低频波长,剖面深度仅为0.099个低频波长,达到小型化的目标,适应内嵌式工作环境。更多还原

【Abstract】 This paper proposes a broadband vertically polarized omnidirectional antenna based on a cone antenna.By loading the top of the cone,short—circuit branches,dielectric material,and lumped elements,the current path in the antenna structure is modified,significantly increasing the effective size of the antenna while achieving miniaturization and broadband matching.With this loaded cone antenna,a three-fold frequency broadband matching(VSWR<2.5) is achieved,with a lateral electrical size of 0.633 wavelengths and a profile depth of only 0.099 wavelengths,meeting the miniaturization goal and suitable for embedded working environments.更多还原
