Wide Band Periodic 2D Leaky-Wave Antenna for Millimeter-Wave Application
IEEE Access, 2023 A wideband periodic leaky-wave antenna (LWA) is proposed in this paper. By using lossy dielectric material inside the wedge-like guide as medium for wave propagation, a leaky mode is excited and results in widening the bandwidth.

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.
