Power distribution circuit and multiplex power distribution circuit

A multiplex power distribution circuit, comprising a plurality of power distribution circuits connected together, wherein each power distribution circuit of the multiplex power distribution circuits comprises:

• a first portion, a second portion and a third portion;
• an isolation element, coupled between the second portion and the third portion;
• a first transmission sub-circuit set on one side of the isolation element, and coupled between the first portion and the second portion;
• and
• a second transmission sub-circuit set on the other side of the isolation element, and coupled between the first portion and the third portion, wherein the first transmission sub-circuit and the second transmission sub-circuit are symmetrically set on both sides of the isolation element;
• wherein the first transmission sub-circuit and the second transmission sub-circuit each comprise a signal transmission line, a first open transmission line and a second open transmission line, and the first open transmission line and the second open transmission are coupled to respective ends of the signal transmission line;
• and
• wherein the first open transmission line comprises:
• a first microstrip line forming an L-shape, wherein a first end of the first microstrip line is coupled vertically to a first end of the signal transmission line;
• and
• a second microstrip line forming a J-shape, wherein a first end of the second microstrip line is coupled to a second end of the first microstrip line, and a second end of the second microstrip line is in an open state.
