摘要
提出了一种磁表面等离子激元螺旋增强的贴片天线。它由一个小环形天线馈电。优化后的天线最终样机整体尺寸为80 mm × 80 mm × 1 mm。仿真结果表明，它具有三个工作频段;−10db阻抗带宽分别为:1.99 ~ 2.52 GHz、3.22 ~ 4.26 GHz和4.71 ~ 5.16 GHz。这三个工作频带都具有具有激发局域SPP模式的散射体的场分布特征。该天线的峰值增益为6.5 dB。
A surface plasmon polariton inspired patch antenna
A patch antenna augmented with a magnetic surface plasmon polariton (SPP) spiral is proposed. It is fed by a small loop antenna. The final prototype of the optimized antenna has an overall size of 80 mm × 80 mm × 1 mm. Simulation results show that it has three working frequency bands; the −10 dB impedance bandwidth of each is: 1.99–2.52 GHz, 3.22–4.26 GHz and 4.71–5.16 GHz. These three working frequency bands all have field distributions characteristic of a scatterer with an excited, localized SPP mode. The peak gain achieved by this antenna is 6.5 dB.
