Two Dimension Beam Scanning 5G Slot array with Single-layer Crossover Substrate integrated

In this paper, a high-frequency 2D beam scanning single-layer slot array based on crossover substrate integrated waveguide (CSIW) is designed. A high-performance 5G cross-waveguide based on substrate integrated waveguide (SIW) is designed in 24Ghz-32Ghz. With this special structure, the problem of SIW slot array can't realize the function of two-dimensional beam scanning successfully solved. The slot array designed in this paper realized a 68°beam scanning angle and 19dBi maximum gain.
