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

Resonance analysis of the leaky-wave antenna
2014 International Symposium on Antennas and Propagation Conference Proceedings, 2014The resonance analysis of the leaky-wave antenna with the microstrip feeding has been presented in this paper. Owing to an open-end structure of the leaky-wave antenna, we analyze the antenna by using the cavity-mode technique. Two conventional leaky-wave antennas with two different lengths, defined by the short and long cases, are shown to examine ...

Security in terahertz WLANs with Leaky wave antennas
Proceedings of the 13th ACM Conference on Security and Privacy in Wireless and Mobile Networks, 2020This paper presents the first security study of THz networks with Leaky Wave Antennas (LWAs). We employ a mix of analytical models and over-the-air experiments to explore the unique security properties of LWA links. We show via both models and experiments that the LWA's angle-frequency coupling leads to non-uniform secrecy capacity across sub-channels ...

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 ...

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 ...

Leaky wave Antenna for mobile phones
International Meeting on Advanced Technologies in Energy and Electrical Engineering, 2020Millimeter wave (mm-wave) is today’s breakthrough frontier for emerging wireless mobile cellular networks, wireless local and personal area networks, simultaneous energy/data transfer, wearable networks, vehicular communications and radar. Directive antennas emerge as a key component in most of these applications driven by the requirement to meet ...

A leaky-wave groove antenna at optical frequency
Journal of Applied Physics, 2012In the framework of nanoantennas functioning at optical frequencies, we present here a new kind of leaky-wave antenna realized as a groove in an aluminum superstrate, supported by a silver substrate. The antenna works in the optical frequency range where the silver acts as a dielectric with equivalent refractive index between zero and one.

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.
