摘要
提出一种新型的带有寄生分枝的双枝倒置F型内置双频天线(IFA)。该天线以传统的平面倒置F型天线(PIFA)为基础,采用单馈点同轴线馈电和带有寄生分枝的双辐射分枝形式,并综合运用分枝弯曲及反复曲折、容性垂直单元加载和在天线辐射分枝上开槽等技术。仿真和实测结果表明,所提出的天线满足900MHz/1800MHz双频段通信系统的要求。
A novel dual-branch internal dual-band inverted-F antenna （IFA） with parasite branch is presented. Based on the traditional planar inverted F-type antenna （PIFA）, the proposed antenna employs a single coaxial feed and two branches with parasite branch, and utilizes the techniques of branch meandering and bending, capacitive perpendicular load and branch slotting. Simulated and tested results show the proposed antenna can meet the requirements of the 900 MHz/1 800 MHz dual-band communication system.
