| Summary: | 碩士 === 國立交通大學 === 電信工程研究所 === 99 === In this thesis, we introduce a dual band beam tilted slotted substrate–integrated -waveguide antenna. The antenna in the thesis is a two- layer structure; the bottom layer is the conventional slotted waveguide, and the waveguide structure is realized by substrate integrated waveguide(SIW); the top layer is a metal patch array which is just above the slot array on the waveguide surface. The two layers both use the Duroid5880 10mil substrate. Conventional slotted waveguide use the fast wave region in the fundamental mode to radiate. By the effect of the top layer patches, we can excite the high order mode of the waveguide structure to acquire another fast wave radiation region.
We use the full wave simulator, HFSS, to analyze the dispersion of the unit cell such that 24GHz and 36GHz are in the fast wave region of the fundamental mode and high order mode respectively, and we organize a 16 units dual band beam tilted slotted substrate-integrated- waveguide and verify the experiment result to the simulation result.
