摘要

本文介绍了一种超材料嵌入贴片天线的电磁模拟的各种观测结果。复合右手左手传输线(CRLH)超材料是研究的超材料。图中显示了嵌入贴片天线的CRLH TL的结构示意图。该结构支撑在厚度为1.59 mm，介电常数为2.4的衬底上。与简单的探针馈电贴片天线相比，超材料嵌入贴片天线有了改进。通过在贴片天线中插入单超材料结构和双超材料结构进行了仿真。嵌入的超材料贴片在增益、天线效率、谐振频率偏移和双频工作方面均有提高。

Simulated resonant characteristics of embedded metamaterial patch antenna

This paper presents various observations, from electromagnetic simulations, of a metamaterial embedded patch antenna. The composite right left handed (CRLH) transmission line (TL) metamaterial is the metamaterial under consideration. The schematic structure of the CRLH TL embedded in a patch antenna is shown. This structure is supported on a substrate of thickness 1.59 mm and dielectric constant 2.4. Compared to a simple probe fed patch antenna there is an improvement for the metamaterial embedded patch. Simulations have been done by inserting a single and a double metamaterial structure in the patch antenna. There is an increase in gain, antenna efficiency, shift in resonant frequency and dual frequency of operation for the embedded metamaterial patch.
