Bow-tie cell artificial surface plasmon polariton transmission line integrated by self-packaging substrate

Abstract

The embodiment of the invention provides a bow-tie cell artificial surface plasmon polariton transmission line integrated by a self-packaging substrate. The transmission line includes a first dielectric plate, a second dielectric plate, a third dielectric plate, a fourth dielectric plate and a fifth dielectric plate, wherein the second dielectric plate is provided with a first blind groove; the third dielectric plate is provided with a third blind groove; a metal layer of the first dielectric plate, a metal layer of the second dielectric plate, a grounding plate on the upper surface of the third dielectric plate, a metal layer on the lower surface of the third dielectric plate, a metal layer of the fourth dielectric plate and a metal layer of the fifth dielectric plate are all wire grounding ends, And each wire grounding end is connected through a metal through hole penetrating through the first dielectric plate, the second dielectric plate, the third dielectric plate, the fourth dielectric plate and the fifth dielectric plate. By adopting the technical scheme of the embodiment of the invention, through an electromagnetic shielding space formed by the first blind groove, the thirdblind groove and the metal through hole, the signal loss in the signal transmission process is reduced, and signals radiated outwards in the signal transmission process are reduced.

Description

technical field [0001] The invention relates to the technical field of microwave transmission, in particular to a bowtie cell artificial surface plasmon transmission line integrated with a self-encapsulating substrate. Background technique [0002] At present, when using various microwave devices, it is necessary to use transmission lines for signal transmission in order to meet people's special requirements for various microwave devices. Existing transmission lines generally have a relatively wide frequency range, which can reduce the loss of the transmission line; however, it is difficult to meet the expected low loss requirements for microwave signals with higher frequencies. In addition, when the transmission line is used in some applications, the transmission line also needs to have some other functions, such as high frequency suppression function and low radiation function. [0003] There are mainly two types of existing transmission lines. The first type of transmiss...

Problems solved by technology

[0004] However, the metal box used in the first type of transmission line has a large volume and weight, and high processing costs. In practical applications, it needs to be mechanically installed, resulting in poor integration, which makes the transmission line Both become very complicated, and do not have high-frequency suppression function; when using the second transmission line, there is more signal leakage during signal transmission, and there are many externally radiated signals, which do not have low loss and low radiation functions
