Magnetically Scannable Leaky Wave Antenna
2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC), 2018This paper discusses the electronically scanning characteristics of a Leaky-Wave Antenna by means of controlling the real part of the leaky-mode complex longitudinal propagation constant at a fixed frequency. The structure is based on a standard rectangular waveguide section with a series of slots cut along its broad wall and loaded with a transversely-

Development of leaky-wave antennas
2016 IEEE International Symposium on Antennas and Propagation (APSURSI), 2016This presentation overviews the development of leaky-wave antennas (LWAs) and the area of leaky waves, starting with the first LWA that was introduced and the early pioneering work of Marcuvitz and Oliner in explaining leaky-wave theory. The development leads up through the present time, where LWAs have seen a renewed interest in the context of ...
