摘要

提出了一种基于欺骗表面等离子激元的准八木天线。在新设计中，天线由共面波导过渡到SSPPs波导、SSPPs平衡器、SSPPs驱动偶极子和两个SSPPs定向器组成。在无衬底的自由空间中，与传统天线相比，驱动偶极子和定向器的长度分别缩短了32%和27%。数值仿真结果表明，该结构具有良好的性能，工作在3ghz时的增益为8.7 dBi。所提出的SSPPs准八木天线具有体积小、性能好等优点，在无线通信系统中具有潜在的应用价值。

A Compact Quasi-Yagi Antenna Based on Spoof Surface Plasmon Polaritons

A novel quasi-Yagi antenna is presented based on spoof surface plasmon polaritons (SSPPs). In the new design, the antenna consists of a transition from a coplanar waveguide to an SSPPs waveguide, an SSPPs balun, an SSPPs driving dipole, and two SSPPs directors. The lengths of the driving dipole and director are approximately reduced by 32% and 27% compared with that of the conventional antenna in the free space without substrate, as a result of high phase constant on the SSPPs. Numerical simulations demonstrate good performance of the proposed structure, which has a gain of 8.7 dBi operating at 3 GHz. The proposed SSPPs quasi-Yagi antenna has potential value in wireless communication systems due to its compact dimension and good performance.
