摘要
基于双锥天线理论基础,为了实现UHF超宽带天线部分结构小型化、简单化,研究并提出了一种工作频率在500~2 500 MHz的改进型平面超宽带领结型天线。采用普通介质板材料,实现了该频段超宽带天线的平面型改进设计。天线结构简单便于制造、调试。实测结果显示,电压驻波比在整个频带内基本小于3.5。该领结型结构具有较好的驻波特性,能够实现对该类传统天线的宽带化、体积小型化改造。
An improved planar UWB bowtie antenna with 500 - 2 500 MHz working frequency is proposed to realize the miniaturization and simplification of partial structure of UHF UWB antenna,which is based on the theory of conical antenna. With common FR4 material,the integrated design of the tie-type emitter array,Microstrip line matching structure and the power splitter structure is realized.The antenna structure is simple and easy to manufacture and debug.And the measured result voltage standing wave ratio（ VSWR） is basically less than 3.5 in the whole band. The structure of the dual cone antenna can greatly reduce the lateral dimension,make full use of the longitudinal space,and realize broadband transformation and miniaturization of the antenna in engineering.
