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 ...

Amplitude-Modulated Leaky-Wave Antennas
IEEE Transactions on Antennas and Propagation, 2021Borrowing the idea of amplitude modulation from classical communications theory, this article proposes and demonstrates a new concept of amplitude-modulated (AM) leaky-wave antennas. In the proposed concept, the traveling wave in a wave-guiding structure serves as the carrier wave whose amplitude is spatially modulated by a predefined modulating ...

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.

2009 IEEE Antennas and Propagation Society International Symposium, 2009
In this paper, a trough leaky-wave antenna is considered that was inspired by the half-width microstrip leaky-wave. The TLW antenna is naturally suitable for flush-mount installation in a metallic body such as an automobile. The radiation characteristics will be investigated in more detail such as the design of the matching cavities and their effect on

Single-Conductor Strip Leaky-Wave Antenna
IEEE Transactions on Antennas and Propagation, 2003The radiation characteristics of a single-conductor strip leaky-wave antenna is investigated. This structure has only a single-conductor strip on a substrate without a background plane. The broadband characteristics of the first higher order space-wave mode render this structure a broadband antenna. These result in a very wide leaky region.

Horn Image Guide Leaky-Wave Antenna
MTT-S International Microwave Symposium Digest, 1981A novel approach for designing a frequency-scanning millimeter-wave antenna is described. The antenna is constructed by using an image wide leaky-wave antenna embedded in a long trough with metal flares along both sides. The optimum flare angle for achieving maximum gain is theoretically predicted.

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 ...
