摘要

研究了半球形介质谐振器天线的对称半截面，提出了一种新型宽带天线。利用Ansoft HFSS求解器研究了探针馈电DRA的输入回波损耗特性、相关谐振模式及其场图以及工作频带上的辐射特性。从单元件低轮廓DRA结构中获得了近40%带宽(S11< - 10dB)的合适辐射图。

Novel wide-band half hemispherical dielectric resonator antenna

A symmetrically half section of a hemispherical dielectric resonator antenna (DRA) has been studied and proposed as a novel broadband antenna. The input return loss characteristics, associated resonant modes and their field patterns and the radiation characteristics over the operating band of a probe-fed DRA have been investigated using Ansoft HFSS solver. Suitable radiation patterns with nearly 40% bandwidth (S11<−10dB) have been obtained from a single element low profile DRA structure.
