Abstract
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.
