Embodiment 1
[0043] Such as figure 1 , 2 , 3, the left-hand microstrip transmission line phase shifter is designed on the PCB board, using Rogers RT / Duroid 5880 dielectric substrate; the first layer and the third layer of the PCB are conductor copper, the thickness is (0.004mm), by The third layer of metal constitutes the ground 1 of the left-hand transmission line, and the middle layer is a dielectric layer 2 with a dielectric constant of 2.2 and a thickness of 0.254 mm. 1 is the input port, 2, 3, 4, and 5 are the output ports, and the line width is 0.78mm.
[0044] The number of states of the power division phase shifter is four as an example, the four loading branches 14 are symmetrically installed on both sides of the power division ring, and the lengths of the loading branches located on the same side of the power division ring are different, and the length difference between the two determines the output phase difference.
[0045] The line width of the wide sides 6 and 7 of the po...
