Optimization of 1-D Unidirectional Leaky-Wave Antennas Based on Partially Reflecting Surfaces
IEEE Transactions on Antennas and Propagation, 2022 In a previous work, we derived optimum conditions for the design of finite-size one-dimensional (1-D) unidirectional leaky-wave antennas (LWAs) in the general case.

Mobile THz communications using photonic assisted beam steering leaky-wave antennas.
Optics Express, 2021 THz communications is envisaged for wide bandwidth mobile communications eventually reaching data capacities exceeding 100 Gbit/s. The technology enabling compact chip-integrated transceivers with highly directive, steerable antennas is the key challenge

IEEE Transactions on Antennas and Propagation, 2021 This article proposes a periodic leaky-wave antenna that is based on a microstrip-fed periodically modulated transverse-slot array in the ground plane. The profile of the transverse-slot array is periodically modulated to introduce a fast space harmonic (

IEEE Transactions on Antennas and Propagation, 2021 In this work, we show that the near field of leaky-wave resonant antennas radiating into a dense medium can be locally represented as a spherical wave in a certain solid angle around broadside using an accurate definition of the phase center.

Fabry-Perot Cavity Leaky Wave Antennas with Tunable Features for Terahertz Applications
Condensed Matter, 2020 Terahertz (THz) radiation is a very appealing band of the electromagnetic spectrum due to its practical applications. In this context, the THz generation and manipulation is an essential part of the technological development.

Analysis and Design of Tunable THz 1-D Leaky-Wave Antennas Based on Nematic Liquid Crystals
Applied Sciences, 2022 The tunable properties of nematic liquid crystals (NLC) are here exploited in a peculiar leaky waveguide with artificial magnetic conductors as the lateral walls, a bottom metal ground plane, and a homogenized metasurface on top to obtain dynamic ...

Analysis and Design of Checkerboard Leaky-Wave Antennas With Low Radar Cross Section
IEEE Open Journal of Antennas and Propagation, 2020 This paper addresses the analysis and design of a new class of metasurface leaky-wave antennas (LWAs) that inherently have low monostatic radar cross section (RCS) for normal incidence parallel polarization.

Gap Waveguide Leaky-Wave Antenna
IEEE 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.
