Leaky Wave Generation Through a Phased-Patch Array [PDF]
SensorsFor this article, we approximated the field of a leaky-wave antenna (LWA) with the field produced by a uniform linear array (ULA). This article aims to provide an initial framework for applications where the generation of an inhomogeneous wave is wished,

IEEE Antennas and Wireless Propagation Letters, 2013 A new composite right/left-handed (CRLH) slotline leaky-wave antenna (LWA) is proposed. The antenna, implemented by loading a slotline with split-ring resonators (SRRs), is designed to exhibit a balanced dispersion relation, with a continuous transition between the left-handed and the right-handed bands at 2.5 GHz.

A Simple High-Gain Millimeter-Wave Leaky-Wave Slot Antenna Based on a Bent Corrugated SIW
IEEE Access, 2020 We propose a bent corrugated substrate integrated waveguide (BCSIW) structure that can be used to design a high gain leaky wave antenna (LWA). The design removes the need for a metallic via fabrication process needed for standard substrate integrated ...

Wide Band Periodic 2D Leaky-Wave Antenna for Millimeter-Wave Application
IEEE Access, 2023 A wideband periodic leaky-wave antenna (LWA) is proposed in this paper. By using lossy dielectric material inside the wedge-like guide as medium for wave propagation, a leaky mode is excited and results in widening the bandwidth.

High Gain Periodic 2-D Leaky-Wave Antenna With Backward Radiation for Millimeter-Wave Band
IEEE Open Journal of Antennas and Propagation, 2021 A two-dimensional (2D) periodic leaky-wave antenna (LWA) is proposed in this article. Using dielectric-filled wedge-like waveguide as medium for wave propagation, the quasi-TEM wave inside the guide is leaked through periodic rings of narrow slots ...
