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 ...
