Ultrawide-Angle and High-Scanning-Rate Leaky Wave Antenna Based on Spoof Surface Plasmon Polaritons
IEEE Transactions on Antennas and Propagation, 2022An ultrawide-angle frequency beam scanning leaky-wave antenna (LWA) with a high scanning rate based on spoof surface plasmon polaritons (SSPPs) waveguide is proposed in this communication. A row of elliptical patches is placed periodically near the SSPPs

A Back-fire to Forward Wide-Angle Beam Steering Leaky-wave Antenna Based on SSPPs
IEEE Transactions on Antennas and Propagation, 2022We demonstrate an efficient back-fire to forward wide-angle beam steering leaky-wave antenna (LWA) based on a large dispersion gradient planar spoof surface plasmon polariton (SSPP) transmission line (TL) with split-ring units.

Proceedings of the IEEE, 2012
This paper gives a basic review and a summary of recent developments for leaky-wave antennas (LWAs). An LWA uses a guiding structure that supports wave propagation along the length of the structure, with the wave radiating or “leaking” continuously along the structure. Such antennas may be uniform, quasi-uniform, or periodic.

Fixed-Frequency Beam Steering Leaky-Wave Antenna With Integrated 2-Bit Phase Shifters
IEEE Transactions on Antennas and Propagation, 2022In this communication, a reconfigurable 2-bit leaky-wave antenna (LWA) is proposed for low-cost fixed-frequency beam-steering applications. The proposed antenna consists of a microstrip transmission line loaded with several branches, a series of 2-bit ...

A History of Leaky Waves and Leaky-Wave Antennas
2019 URSI International Symposium on Electromagnetic Theory (EMTS), 2019The history of leaky waves and leaky-wave antennas is an interesting one, with much of the theory being put on a firm foundation in the 1950s and 1960s by early pioneers such as Nathan Marcuvitz and Arthur A. Oliner. Rapid development of leaky-wave antennas took place after the foundation was established, and the development spread to areas such as ...
