Full‐Space Scanning Leaky‐Wave Antenna Utilising Spoof Surface Plasmon Polaritons
Electronics Letters, Volume 61, Issue 1, January/December 2025.In this paper, we present a novel spoof surface plasmon polariton leaky‐wave antenna (SSPP‐LWA) capable of full‐space beam scanning. The proposed antenna achieves full‐space beam scanning from ‐90° to +90° across the frequency band of 9.8–13.3 GHz, with a high scanning rate of 5.94° per 1% frequency variation.
