Abstract

The invention relates to a back-to-back transition structure from a coplanar waveguide to a dielectric waveguide. The transition structure includes two transition pieces; It is fixed with the coplanar waveguide at the two joints; each adapter is provided with a groove, and the dielectric waveguide is stuck in the groove, which solves the problem of maintaining the relative position of the dielectric waveguide and the coplanar waveguide as two separate parts in practical applications constant question. And in the second fixing part of the present invention, the terminal of the rising wedge-shaped straight upward slope does not contact the wedge-shaped dielectric waveguide, preventing the energy of the wave propagating between the dielectric waveguide and the coplanar waveguide from being transmitted to the second fixing part, reducing the energy Loss, realizing low-loss transition from back-to-back coplanar waveguide to dielectric waveguide.

Description

technical field [0001] The invention relates to the field of communication in the terahertz frequency band, in particular to a transition structure from back-to-back coplanar waveguides to dielectric waveguides. Background technique [0002] Dielectric waveguides are widely used in terahertz transmission systems as an alternative to metal transmission lines in the terahertz band because of their low loss, wide bandwidth, low cost, and easy processing. However, since the material of the dielectric waveguide is different from that of metal, and the main mode of transmission is different, the design of the transition structure from metal transmission lines such as microstrip lines and coplanar waveguides to the dielectric waveguide is very important. At the same time, due to the small size of the terahertz transmission system, the metal transmission line and the dielectric waveguide are discrete devices. How to ensure the relative position of the two in practical applications h...
