ABSTRACT:
A printed 180 degree differential phase shifter includes a short nonuniform nonregular line and a uniform transmission line. The nonuniform nonregular line consists of two broadside coupled lines of both sides of a thin dielectric substrate. These highly magnetically coupled lines have short opposite connections (short circuits) connecting the coupled lines with a ground of the uniform line. An opposite input and output of the coupled lines are electrically interconnected with input and output transmission lines having equal impedances. The coupled lines are distant from the ground of the uniform line which can be any transmission line having an electrical length equal to the electrical length of the nonuniform nonregular line.
