Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0029] The present invention uses the first resonant mode of the slot line resonator and the two resonant modes excited by the microstrip line-slot line-microstrip line coupling structure to design a broadband vertical microstrip line-microstrip line transition device. For a two-layer or multi-layer dielectric board structure, a broadband vertical transition is formed by electromagnetically coupling the slot line resonators on the common ground with the top and bottom microstrip line resonators.

[0030] Such as figure 1 as shown, figure 1 It is a three-dimensional structural schematic diagram of a broadband vertical transition device with a center-symmetric feed structure provided by the present invention. The broadban...

Abstract

The invention discloses a broadband vertical transition device. The broadband vertical transition device is of a two-layer or multi-layer dielectric slab structure and comprises a trough line resonator which is arranged on a public area between layers of the two-layer or multi-layer dielectric slab structure and has a regular shape, a microstrip line resonator arranged on the top layer of the two-layer or multi-layer dielectric slab structure, and a microstrip line resonator arranged on the bottom layer of the two-layer or multi-layer dielectric slab structure, wherein both the microstrip line resonator arranged on the top layer and the microstrip line resonator arranged on the bottom layer are perpendicular to the trough line resonator arranged on the public area, and the microstrip line resonator arranged on the top layer and the microstrip line resonator arranged on the bottom layer are completely consistent and symmetrical about the public area in the vertical direction. The broadband vertical transition device has broadband transmission characteristic and can achieve smoothing response of three in-band transmission poles. The broadband vertical transition device is clear in design principle, simple in structure, easy to manufacture and low in cost.

Description

technical field [0001] The present invention relates to the application of broadband and ultra-wideband communication systems, specifically a radio frequency or microwave integrated circuit designed with double-layer dielectric or multi-layer dielectric structure, especially a broadband vertical transition device. Background technique [0002] Usually for radio frequency integrated circuits and microwave integrated circuits that need to use advanced multi-layer manufacturing processes, it is very necessary to research and develop broadband vertical transitions with broadband characteristics. The vertical transition is a key component, which can be used to transfer radio frequency or microwave signals from one layer to another, and maintain almost lossless transmission in a wider frequency band. [0003] There are mainly three types of broadband vertical transitions currently developed: via-coupled transitions, cavity-coupled transitions, and slot-coupled transitions, among w...
