Summary: | The invention relates to the technical field of anti-crosstalk of parallel microstrip lines, in particular to a structure for reducing electromagnetic interference of parallel microstrip lines in a printed circuit board. The structure is based on sub-wavelength period microstrip lines, is arranged between the parallel microstrip lines, and comprises the following three structures: a first structure is a sub-wavelength period microstrip line structure of which two ends are connected with resistors; a second structure, one end of the second structure is connected with a resistor, and the other end of the second structure is connected to a sub-wavelength period microstrip line structure of a current return path through a metal tube; a third structure, one end of the third structure is connected with the resistor, and the other end of the third structure is not connected with any component. Compared with a traditional microstrip line for isolating electromagnetic interference between parallel microstrip lines, th |
