Abstract

The utilization of substrate integrated waveguide (SIW) higher-order modes can significantly reduce the number of metal posts and thus simplify the component structure. In this paper, two wideband excitation structures for higher-order modes in SIWs are proposed and investigated to implement slot arrays. Two parallel coupling slots along the SIW are used to excite the TE₄₀ mode. The excitation structures exhibit broad bandwidth and good mode purity. Moreover, they can be extended to realize transitions exciting TE₆₀, TE₈₀, . . ., TE_m0[m = 6, 8, . . . 2 x (n + 3), n is a natural number] modes. As application examples, a 4 x 4-element slot array is designed. Measured results demonstrate that the slot array inherits the merits of the excitation and shows a simple structure, broadside radiation, high aperture efficiency, and good radiation efficiency.
