Wide Band Periodic 2D Leaky-Wave Antenna for Millimeter-Wave Application

open access: yesIEEE 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.

Gap Waveguide Leaky-Wave Antenna [PDF]

open access: yesIEEE Transactions on Antennas and Propagation, 2016
A novel leaky wave antenna, realized using gap waveguide concept, is here proposed. Both, the feeding structure and the antenna are realized in groove gap waveguide technology, thus simplifying the whole structure. A complete design procedure, starting from a given groove waveguide to the final radiation mechanism, is described in this paper.

Leaky Wave Generation Through a Phased-Patch Array [PDF]

open access: yesSensors
For 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,

The leaky lens: a broad-band fixed-beam leaky-wave antenna [PDF]

open access: yesIEEE Transactions on Antennas and Propagation, 2005
A novel type of leaky-wave antenna is presented. Differently from previously reported leaky-wave antennas, it is characterized by a constant beam direction over a very wide range of frequencies. The radiation originates at a slot etched at the interface between air and a dense dielectric, which is shaped to form a cylinder of elliptical cross sections ...

A Ka-band one-dimensional beam scanning leaky-wave antenna based on liquid crystal [PDF]

open access: yesScientific Reports
Fixed frequency beam-scanning leaky-wave antennas have been a focus of attention for many scholars in recent years, and numerous related results have been obtained. However, these antennas suffer from several issues such as small beam-scanning range, low
