title = "Multifunctional Reconfigurable Spoof Surface Plasmon Polariton (SPP) Antenna",
abstract = "A switchable binary patterned surface plasmon polariton (SPP) leaky-wave antenna is proposed in this paper. The antenna consists of an ultra-thin corrugated metallic structure on 2mm thick substrate which supports highly confined spoof surface plasmon polaritons (SPPs). The antenna is fed by a coplanar waveguide (CPW) structure. To achieve a smooth conversion from the spatial mode in the CPW to the flat mode in the spoof surface plasmon (SPP) structure, two sector-like transition sections are introduced to suppress the return loss. Two varactors are integrated inside the SSP unit-cells to enable a reconfigurable surface impedance pattern. By actively modulating the surface impedance, a switching mechanism between the guided transmission mode and the leaky wave mode is achieved with a high degree of robustness. Furthermore, multi-directional beam steering from the broadside to endfire can be synthesized with this antenna with high efficiency. A highly directional pattern with a maximum realized gain that varies from 6 dBi to 8 dBi is demonstrated at 6 GHz.",
