In this paper, a wide-range leaky-wave antenna with fast scanning rate and open-stopband (OSB) suppression based on microstrip spoof surface plasmon polaritons (MSSPPs) is proposed. First, the high-scanning-rate theory is analyzed. And based on the theory, the MSSPPs is used to radiate the fan beam rather than quasi-omnidirectional beam. In order to suppress the OSB, a capacitive slot is introduced using the proposed method of impedance matching. The prototype of the proposed antenna is fabricated and the measured results show that the antenna has 140° scanning range from −72° to 68° with the scanning rate of 8.8 and reflection coefficient lower than −10 dB in 8.7–10.2 GHz.
