[Abstract]:The substrate integrated waveguide is a new type of waveguide transmission line, which has a guided wave structure similar to that of the traditional dielectric filled waveguide. The theoretical study shows that the two waveguides also have similar transmission characteristics. Therefore, the substrate integrated waveguide has the advantages of low insertion loss, large power capacity, low radiation and so on. At the same time, it also has the advantages of low profile of microstrip line, small size, easy processing and easy integration with other planar structures. In this paper, four microwave passive devices based on substrate integrated waveguide structure: 1) an evanescent mode filter based on stereoscopic folded half-mode SIW is designed. The operating frequency band is 2.04-3.28GHz, the relative bandwidth is 46.61, and the out-of-band suppression is better than 25dB / 2) an all-mode power divider based on SIW is designed. The power distribution of four output ports can be realized in the frequency range of 9.4-11GHz. The half-mode SIW two-way power divider is designed and applied to the four-way power divider with the original full-mode structure. In this paper, a phase shifter based on substrate integrated waveguide is designed, which can realize the power distribution of four output ports in the frequency range of 7.79-9.86GHz. The equivalent circuit of loaded cylindrical inductor pin in waveguide is discussed. A microwave phase shifter with 4 pairs of inductor pins is designed. A kind of porous directional coupler based on substrate integrated waveguide is designed in the frequency range of 9.32-9.68 GHz (relative bandwidth 3.79), which can realize 90 擄鹵5 擄phase offset. The coupling port can be realized in the frequency range of 5.52-6.58GHz. On this basis, a directional coupler based on half-mode substrate integrated waveguide is designed. The coupling port coupling of -6dB can be realized in the frequency range of 5.03-8.51GHz. Compared with the full-mode structure, the transverse dimension is reduced by 51.9 and the longitudinal dimension by 48.7. All of the above microwave passive device models are in CST Microwave Studio? The corresponding model is established in the electromagnetic simulation software, and the optimization work and physical processing are carried out, and the actual use of Agilent N5227A vector network analyzer is tested. The test results show that the experimental results are in good agreement with the simulation results. The correctness of the design idea is proved. The passive devices have been designed with low profile and light weight, which can be used in the communication and electronic systems in the corresponding frequency band.
