Problems solved by technology

However, the transmission characteristics of microstrip lines and coplanar lines depend to a large extent on the dielectric substrate material, which will cause dielectric loss. Such planar transmission lines have high dielectric loss and conductor loss in the millimeter wave spectrum.
In addition, the dielectric substrate will excite unwanted surface wave modes, and the high-order mode radiation loss will also affect the transmission performance
Therefore, the loss of planar transmission lines is small at low frequencies, but at high frequencies, problems such as signal loss and attenuation will occur, and the propagation loss is too large, which greatly affects the propagation of signals
[0005] In summary, the existing transmission lines cannot balance the dielectric loss and bandwidth coverage at the same time

Embodiment Construction

[0044] Next, the technical solutions in the embodiments of the present invention will be apparent from the embodiment of the present invention, and it is clearly described, and it is understood that the described embodiments are merely embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.

[0045] In addition to the demand for low loss, a high communication rate With the growing demand, the operating bandwidth of the transmission line directly affect the performance of the associated device design, thus covering made from a direct current (DC) to the millimeter wave / terahertz (a THz) large bandwidth the concept of. Therefore, DC to terahertz transmission line has received extensive attention in various fields. Thus, a large connecting low power, low latency, high reliability, ultra-low power consumption and ...

Abstract

Embodiments of the present invention provide a broadband transmission line and a transmission system, which are applied in the field of communication technology, and may include: a coplanar waveguide transmission line, a gap layer, and a gap waveguide; the coplanar waveguide transmission line, the gap layer, and a gap waveguide form the main part of the transmission line, wherein , the inverted coplanar waveguide transmission line is located above the gap waveguide, and there is a gap layer between the upper surface of the gap waveguide and the coplanar waveguide transmission line. In this way, the problem of high loss at high frequencies can be avoided while extending the bandwidth coverage.

Description

Technical field [0001] The present invention relates to the field of communication technologies, particularly to a transmission line and broadband transmission systems. Background technique [0002] Next generation mobile communication system of the fifth generation mobile communication network (5th generation mobile networks or 5th generationwireless systems, 5G) is a demand for the development of mobile communication, 5G communications band comprises a Sub-6G and millimeter-wave bands. Sub-6G is the use of the following 6GHz bandwidth resources to develop 5G, with its covering ability, good penetration, it has been gradually commercial. 2019 World Radiocommunication Conference (WRC-19) announced 5G millimeter wave frequency band has a wide spectrum, high stability, good direction, a clean spectrum and other advantages, in the future with a very large potential for development. Transmission lines are guided wave propagation medium, and also constitutes an important part of micro...
