Abstract
The present disclosure relates to a signal transmission line structure, a phase shifter and an antenna. The signal transmission line structure includes a dielectric substrate, the dielectric substrate has a first surface and a second surface opposite to each other, and the first surface is provided with a first transmission line , the second surface is provided with a second transmission line; the first transmission line is composed of a plurality of first conductive patches, and a plurality of the first conductive patches are sequentially arranged along the extension direction of the first transmission line, And there is a gap between two adjacent first conductive patches, and each of the first conductive patches is electrically connected to the second transmission line, so that the signal transmission line structure can provide a larger phase shift It reduces the matching pressure of the antenna array and saves space.
Description
technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a signal transmission line structure, a phase shifter, and an antenna. Background technique [0002] Signal transmission lines are used to transmit signals. At present, the 5G network has covered a large area, and the 5G base station antenna has put forward higher requirements for the radiation pattern. Due to the limitation of the antenna size, the matching requirements of the antenna have also become very high. [0003] The signal transmission line structure in the prior art specifically implements the phase shift through slow-wave lines, but there are too many wires in this way, resulting in a large space occupancy rate of the signal transmission line structure. SUMMARY OF THE INVENTION [0004] In order to solve the above technical problems or at least partially solve the above technical problems, the present disclosure provides a signal transmission...
