Design of Spoof Surface Plasmon Polariton Conical Beam Antenna Combining Particle Swarm Optimization for Haze-detecting

In this paper, a spoof surface plasmon polariton (SSPP) conical beam antenna is proposed for haze-detecting mobile station. It is composed of a smoothly connected truncated- cone with multilayered toothed structure along the cylindrical bar. And the antenna combines the whip performance and SSPP effect to construct the conical beam. After optimization of PSO, the antenna achieves impedance bandwidth 20% over 320 MHz ~ 525 MHz, the rotation symmetrical beam covers the upper half space and satisfies the air link gain demands to haze-detecting. The maximum size is $0.39\lambda ^{\star }0.39\lambda ^{\star }0.55\lambda (\phi 365\mathrm {m}\mathrm {m}^{\star }\mathrm {h}512.9\mathrm {m}\mathrm {m})$, which is very compact, lightweight, and being suitable for 3D printing.
