Leaky Wave Fed Substrate Integrated Horn Antenna [PDF]

open access: yes, 2020
Linearly flaring horn antennas typically suffer from low aperture efficiency, especially for large apertures. While spline horns can improve the aperture efficiency, this is at the cost of increased and more complex profile. This paper introduces a novel

High Gain Periodic 2-D Leaky-Wave Antenna With Backward Radiation for Millimeter-Wave Band

open access: yesIEEE 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 ...

Single-Side-Scanning Surface Waveguide Leaky-Wave Antenna Using Spoof Surface Plasmon Excitation

open access: yesIEEE Access, 2018
A surface waveguide (SWG) leaky-wave antenna featuring directional single-side beam scanning capability is presented. A novelty of the design is that transition design utilizes the spoof surface plasmon (SSP) as an intermedia to feed the SWG, which ...

Reconfigurable THz Fixed-Frequency Beamscanning Through a Liquid-Crystal-Loaded Leaky Waveguide Operating in Its Fundamental TE Mode

open access: yesIEEE Access, 2023
A rectangular metallic leaky waveguide loaded with liquid crystals (LC) and operating in its fundamental TE mode at 1 THz is proposed to mitigate the well-known trade-off between directivity and tunable angular range of dynamic beamscanning antennas. The

Continuous Scan of Radiation Beam from a Half-Width Microstrip Leaky-Wave Antenna at a Fixed Operating Frequency

open access: yes, 2021
A leaky-wave antenna (LWA) that can scan a beam continuously at a fixed operating frequency is presented in this paper. A half-width (HW) microstrip LWA is considered as the main radiating element in which one edge of the microstrip is shorted to the ...
