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,

Rigorous Evaluation of Losses in Uniform Leaky-Wave Antennas
IEEE Transactions on Antennas and Propagation, 2019 General formulas are proposed for thoroughly evaluating the radiation efficiency of traveling-wave antennas operating in any radiating regime. Indeed, existing theoretical models only work in the scanned-beam region, where the radiating mode is ...

B7. Leaky-Wave Coaxial Antenna [PDF]
2013 30th National Radio Science Conference (NRSC), 2013 Analysis and design of a coaxial leaky wave antenna with partially reflecting outer surface are presented. The leaky wave properties are controlled by adjusting the surface impedance of the outer surface, the filling dielectric constant and the dimensions of the inner and outer radii.

Reconfigurable Antennas Based on Pure Water
IEEE Open Journal of Antennas and Propagation, 2021 This paper is concerned with the design of reconfigurable antennas based on pure water. Being a transparent, flexible, and readily available liquid, pure water can form a cylindrical stream that can be used to guide a leaky electromagnetic wave.
