摘要

提出了一种覆盖高介电常数介质层的小型金属体积天线。这是一种水滴形天线，由于其几何形状和特殊结构，被认为具有宽带辐射特性。电介质层有助于保持天线的尺寸小。为了避免由于该层而导致的q因子的不希望的增加，其厚度保持尽可能小。采用辅助源法对结构进行了数值模拟。给出了特定频率下的场分布以及结构的频率响应。

Analyses of voluminous metallic antenna covered with dielectric layer

Small metallic voluminous antenna covered with a high permittivity dielectric layer is presented. This is a drop-shaped antenna that is supposed to have a wideband radiation characteristics due to its geometry and special structure. The dielectric layer helps to keep the size of the antenna small. To avoid undesired increase of the Q-factor due to this layer its thickness is kept as small as possible. The structure was numerically simulated using the method of auxiliary sources (MAS). The field distributions for particular frequencies are presented together with the frequency response of the investigated structure.
