The invention relates to a signal transmission line structure, a phase shifter and an antenna; the signal transmission line structure comprises a dielectric substrate; the dielectric substrate is provided with a first surface and a second surface opposite to each other; the first surface is provided with a first transmission line, and the second surface is provided with a second transmission line; the first transmission line is composed of a plurality of first conductive patches; the first conductive patches are sequentially arranged in the extending direction of the first transmission line; a gap is formed between every two adjacent first conductive patches; and all the first conductive patches are electrically connected with the second transmission line, so that the signal transmission line structure can provide larger phase offset, the phase matching pressure of an antenna array is reduced, and the space is saved.
Description
technical field [0001] The present disclosure relates to the technical field of communication, 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 on 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 realizes the phase shift through the slow-wave line, but this method has too many windings, resulting in a large space occupancy rate of the signal transmission line structure. Contents of the invention [0004] In order to solve the above technical problems or at least partly solve the above technical problems, the present disclosure provides a signal transmission line stru...
