本文提出了一种紧凑的宽带频率扫描欺骗表面等离子体激元（SSPP）为基础的设计高效端射辐射与高场约束。通过色散工程，在工作频率范围内获得了高度受限的场分布。所提出的SSPP天线已经实现了在其他工作频率下在X波段中的连续贯穿端射扫描，这对于基于SSPP的天线来说通常难以获得。在所提出的设计方法中，swore形的表面等离子体天线的两个边缘波纹与矩形凹槽的阵列，有效地限制成一个缓慢的行波的电磁场。沿着两个边缘的表面阻抗被设计为在操作频率下不同，以迫使表面电流优先沿着天线的任一边缘流动到不同程度。在X波段，总尺寸为（55 × 30）mm 2的设计获得了4 GHz的宽带，高峰增益为9.8 dBi，峰值效率约为95%。该天线已被进一步测试实验扫描应用的目标定位也。
This paper proposes a compact broadband frequency scanning spoof surface plasmon polariton (SSPP) based design for efficient endfire radiations with high field confinement. Through the dispersion engineering, highly confined field distribution has been obtained in the operating frequency region. The proposed SSPP antenna has achieved a continuous through endfire scanning in the X-band at other operating frequencies which is in general difficult to obtain for SSPP based antennas. In the proposed design methodology, the swore-shaped surface plasmon antenna has both edges corrugated with an array of rectangular grooves which effectively confines the electromagnetic field into a slow travelling wave. The surface impedances along both edges were engineered to be different at operating frequencies as to force the surface current to preferentially flow along either edge of the antenna to a different extent. The design with overall dimensions of (55 × 30)mm2has achieved a broadband of 4 GHz with high peak measured gain of 9.8 dBi and peak efficiency of about 95 percent in the X-band. The antenna has been further tested experimentally for scanning application of target location also.
