Summary:In this paper, a dual-radiation mode leaky-wave antenna (LWA) with flat-topped and end-fire beams based on the composite structure is proposed. A four-element LWA array using substrate integrated waveguide (SIW) technology is designed to generate four -1st space harmonics with different beam pointing angles, which are weighted and superimposed to form a flat-topped and wide-angle beam (including the broadside direction). The structure of printed tapered periodic leaky-wave strips realizes the end-fire directional radiation beam with broadband characteristics. Simulation results demonstrate the effectiveness of the dual-radiation mode composite structure proposed in this paper.
