摘要
提出了一种紧凑型宽带平面天线,可工作在DVB-T频段。该天线由两个对称辐射臂组成,辐射臂中引入了多个圆弧曲线段,可以有效减小振子末端的反射电流,展宽了天线的工作带宽。天线整体尺寸为268mm×115.5mm,测试结果显示VSWR≤2的频段为440-1326MHz,覆盖了470-862MHz的DVB-T频段。该天线易加工、便于安装放置,且方向图有较好的全向特性。
A compact wideband planar antenna working in the DVB-T(Digital Video Broadcasting-Terrestrial) frequency band is proposed. The antenna consists of two symmetrical radiation patches. By using multiple circular arc curve segments, the reflection at the end of the radiation patch can be effectively reduced, as well as wideband impedance characteristics are achieved. The overall size of the antenna is 246.7mm×106.5mm. The measured results show that VSWR less than or equal to 2 was obtained in the 440-1326 MHz, covered the DVB-T band(470-862 MHz). The antenna is easy to be processed and installed. The proposed antenna presents omnidirectional radiation patterns across the whole operating band.
