一种小型化超宽带共面波导馈电蘑菇形单极子天线OACSTPCD
Miniature ultra-wideband CPW-fed monopole antenna with mushroom-shaped structure
提出一种简单的尺寸为23 mm×25 mm×1 mm小型化超宽带共面波导馈电单极子天线,它由梯形槽口接地板、蘑菇形辐射贴片和RF4介质板构成.详细讨论了梯形槽口结构和矩形渐变结构对阻抗特性的影响,分析了天线的辐射特性和增益特性,获得该天线的回波损耗小于-10 dB的带宽为3～13 GHz,在3～11 GHz频段内具有全向性,增益变化范围是2.2～5 dB.
A simple and compact ultra-wideband monopole antenna fed by coplanar waveguide (CPW) is presented. The overall size of the antenna is 23 mm×25 mm×1 mm, which consists of a ground plane with trapezium-shaped slot and a mush-room-shaped radiating patch printed on the same side of the substrate. By optimizing trapezoid slot and loading rectangular gradient structure, the impedance matching characteristics is analyzed and a wide impedance bandwidth from 3 GHz to…查看全部>>
