A Leaky Wave Antenna With Capability of Fixed-Frequency Beamforming Scanning
IEEE Transactions on Antennas and Propagation, 2023A novel electrically controlled leaky wave antenna (LWA) with the capability of fixed-frequency beamforming scanning is proposed in this communication. The antenna is designed on a substrate-integrated waveguide (SIW), and the slot period of the antenna ...

Millimeter waveguides, such as coplanar lines, microstrip lines and dielectric guides, are open structures where energy leakage is bound to occur. This leakage can occur, for example, when there are discontinuities in the guiding structure, or perhaps when the guide is excited in an inappropriate mode.

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.

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 ...

A Broadband Fixed-Beam Leaky-Wave Antenna
IEEE Transactions on Antennas and Propagation, 2023In point-to-point communication, antennas are often required to radiate a broadband signal in a specific direction. Traditional leaky-wave antennas (LWAs) have the features of low cost and high gain but also the frequency-beam-scanning property, which is

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.
