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.
