Wide-angle frequency scanning of the antenna is achieved by combining the slow-wave dispersion characteristics of Spoof Surface Plasmon Polaritons and the left-and-right-composite-handed characteristics of the complementary split ring resonator structure. The simulated and experimental results show that, with the increase of frequency, the radiation mode of the antenna gradually changed from slow-wave mode to fast-wave radiation mode, and the pattern changed continuously. The scanning region of the main beams proposed covers 110° in φ=0° plane when the frequency increases from 8GHz to 15GHz, and the gain of the antenna kept between 7dBi and 10.4dBi.
