Problems solved by technology

Although this type of substrate-integrated non-radiative dielectric waveguide solves the problem of difficult positioning in processing, it needs to be covered with two metal plates just like the classic non-radiative dielectric waveguide. The processing is still cumbersome, and it is still a three-dimensional circuit.

Abstract

The invention discloses a novel filter based on a substrate integrated non-radiative dielectric waveguide. First, a non-radiative dielectric waveguide structure is obtained by directly punching holes in a printed circuit board, filtration is achieved through the uneven stepped impedance structure on the basis of the waveguide structure, and the stepped impedance structure is also obtained by punching holes in the substrate integrated non-radiative dielectric waveguide. The novel filter is simple in design structure, good in performance and easy to machine; compared with a filter based on a traditional non-radiative dielectric waveguide, the novel filter is higher in structure plane stability, can be integrated with a circuit of a planar structure more easily, and has considerable application prospects in a microwave millimeter wave integrated circuit system.

Description

technical field [0001] The invention relates to a novel filter based on substrate integrated non-radiative dielectric waveguide, which belongs to the field of microwave technology. Background technique [0002] With the development of the microwave frequency band to the high frequency band, especially the millimeter wave spectrum band, the non-radiative dielectric waveguide has become an important component in the circuit design of the millimeter wave band because of its low radiation loss characteristics at structural bends and discontinuities. However, due to the instability of its structure, the traditional non-radiative dielectric waveguide is difficult to process and difficult to integrate with planar circuits, which greatly limits the development and application of the traditional non-radiative dielectric waveguide. [0003] The proposal of the substrate-integrated non-radiative dielectric waveguide solves the problem of unstable structure of the traditional non-radiat...
