摘要

提出了一种适用于宽带无线应用的新型高增益介质谐振器天线。该天线由一个中空的圆柱形介电谐振器(DR)组成，DR内插入两个介电截锥组件，其介电截锥具有不同的介电常数。采用合适的探头激励系统和在第一截短介质锥基部与接地面之间实现气隙，进一步增加天线带宽。采用基于有限积分技术(FIT)的全波商用软件对天线进行了分析和设计，并采用奇点提取方法(SEM)提取了辐射结构中发生的主要谐振过程的信息。

A novel wideband multi-permittivity composite dielectric resonator antenna for wireless applications

A novel high-gain dielectric resonator antenna (DRA) for wideband wireless applications is presented. The antenna is composed of a hollow cylindrical dielectric resonator (DR) inside which an assembly of two dielectric truncated cones having different permittivities are inserted. A suitable probe excitation system and an air gap, realized between the base of the first truncated dielectric cone and the ground plane, are used to further increase the antenna bandwidth. A full-wave commercial software based on the finite integration technique (FIT) has been used to analyze and design the antenna, while the singularity-extraction method (SEM) has been adopted to extract information about the main resonant processes taking place in the proposed radiating structure.
