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 ...

Design of a Compact Omnidirectional Leaky-Wave Antenna Fed by Higher Order Mode
IEEE Transactions on Antennas and Propagation, 2022This article presents a novel leaky-wave antenna (LWA) based on a dielectric-filled rectangular waveguide (RWG) and fed by a higher order mode. The proposed quasi-uniform LWA has a compact configuration that is suitable for microwave applications ...

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.

Direction Finding of RFID Tags in UHF Band Using a Passive Beam-Scanning Leaky-Wave Antenna
IEEE Journal of Radio Frequency Identification, 2022This work proposes a novel system for location applications of RFID tags in UHF band. The system is based on a frequency-scanning leaky-wave antenna (LWA), commodity hardware and Angle-of-Arrival (AoA) estimation of the signal reflected from RFID tags ...

Composite Right/Left-Handed Leaky-Wave Antenna With High Scanning Rate
IEEE Antennas and Wireless Propagation Letters, 2022The scanning rate of a composite right/left-handed (CRLH) leaky-wave antenna (LWA) is usually determined by the dispersive behavior of the corresponding CRLH unit cell.

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

2018 Fifth International Conference on Millimeter-Wave and Terahertz Technologies (MMWaTT), 2018
Dirac leaky-wave antennas (DLWAs) are derived from photonic crystals exhibiting Dirac cone dispersion around their $\Gamma$-point. DLWAs provide high directive beams and continuous frequency beam scanning, non-fluctuating leakage constant and real non-zero Bloch impedance at and around broadside, due to the closed and linear Dirac dispersion relation ...
