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