摘要

提出了一种小型化圆盘单极天线的新方法。通过智能地在天线周围加载高介电常数的介电材料，使天线的物理尺寸小型化。为了保持阻抗带宽特性，采用了空间四分之一波变压器。仿真结果表明，该结构在保持阻抗带宽的同时，结构的物理尺寸减小了58.4%。

Can ultrawideband antennas be miniaturized effectively by dielectric loading?

A novel approach for miniaturization of disc monopole antennas is presented. The physical size of the antenna has been miniaturized by loading a dielectric material of high dielectric constant around the antenna in an intelligent manner. In order to maintain the impedance bandwidth characteristics, a spatial quarter wave transformer was applied. Simulations of the structure showed that the impedance bandwidth was conserved while the physical size of the structure was reduced by 58.4%.
