Amplitude-Modulated Leaky-Wave Antennas

IEEE Transactions on Antennas and Propagation, 2021
Borrowing 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 ...

A Simple Technique for Open-Stopband Suppression in Periodic Leaky-Wave Antennas Using Two Nonidentical Elements Per Unit Cell

IEEE Transactions on Antennas and Propagation, 2018
A simple technique is presented for the complete suppression of the open stopband in periodic leaky-wave antennas using two similar but nonidentical elements per unit cell.

A History of Leaky Waves and Leaky-Wave Antennas

2019 URSI International Symposium on Electromagnetic Theory (EMTS), 2019
The 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 ...

Leaky-wave antennas I: Rectangular waveguides

IEEE Transactions on Antennas and Propagation, 1959
A microwave network approach is employed for the description and analysis of leaky-wave antennas. This approach is based on a transverse resonance procedure which yields the complex propagation constants for the leaky waves. A perturbation technique is then applied to the resonance equation to obtain results in simple and practical form.

Double-Periodic Patch-Loaded Spoof Surface Plasmon Polariton Leaky-Wave Antennas With Suppressed Open-Stop Band Effects

IEEE Antennas and Wireless Propagation Letters, 2023
A leaky-wave antenna (LWA) based on split-ring-shaped spoof surface plasmon polaritons (SSPPs) is designed, simulated, and measured. We proposed a double-periodic patch-loaded method to suppress the open-stop band (OSB) effect and introduced an SSPP ...

Dual-Band Asymmetric Leaky-Wave Antennas for Circular Polarization and Simultaneous Dual Beam Scanning

IEEE Transactions on Antennas and Propagation, 2021
In this article, two configurations of novel dual-band half-mode substrate integrated waveguide (HMSIW) leaky-wave antennas are presented. The first proposed antenna radiates linearly polarized (LP) waves in the lower band and circularly polarized waves ...
