A novel spoof surface plasmon polariton leaky-wave antenna (SSPP-LWA) capable of full-space beam scanning is proposed in this letter. First, the surface plasmon polariton (SPPs) unit and its corresponding transmission line are carefully designed, and the underlying mechanism to achieve full-space scanning is analysed based on a monopole array structure. Specifically, a spoof surface plasmon polariton (SSPP) transmission line combined with a semicircular, three-dimensionally loaded radiating patch is introduced and equivalently modelled as a monopole radiating element. Subsequently, the proposed LWA is realised by employing a monopole array composed of 12 identical radiating elements. Simulation results verify that the antenna achieves continuous beam scanning from -90° to +90° within the frequency range of 9.8–13.3 GHz, exhibiting a high scanning rate of up to 5.94°/%, with an average gain of approximately 9 dBi. Benefiting from its excellent scanning capability and stable radiation characteristics, this antenna demonstrates significant potential for target detection and tracking applications in radar systems.
