摘要：
A leaky-wave antenna with circular polarization (CP) radiation characteristic is presented in this paper. The antenna has no ground plane, and is fed with a one-to-two divider based on co-planar-waveguide. The radiation is generated by perturbation of periodic orthogonal strips on the spoof surface plasmon polaritons (SSPPs) transmission lines. The results show that good axial ratio can be achieved at the main beam direction of -31 degrees at 12 GHz, and high efficiency can be obtained.
