圆柱形介质谐振器天线阵列设计

一种圆柱形介质谐振器天线阵列设计

内容简介：在圆柱形介质谐振器天线单元分析的基础上，设计了一种4单元介质谐振器天线阵列。天线阵采用微带线馈电网络，保证单元之间满足相位匹配关系，使该天线阵列具有良好的定向辐射特性，而且在带宽方面满足要求。

Abstract：A dielectric resonator antenna （ DRA ） array with 4 units is developed. This design is based on a single unit of the cylindrical DRA analyzed. The antenna array is feed by a mierostrip network; therefore the phase match relation between each unit is satisfied. The proposed technique makes the antenna array with better performance of directional radiation patterns, as well as with a suitable bandwidth.
