In this paper, the method of least squares is used to the optimum design of the modified coupled-line phase shifter, which used the dissipation effect and dispersion relations of the microstrip coupled lines in their microwave circuit models. An error function is constructed based on the even- and odd-mode analysis, impedance, transmission and scattering matrices of the phase shifter, which is a frequency...
In this paper, the method of least squares is used to the optimum design of the modified Schiffman phase shifter, which used the dissipation effect and dispersion relations of the microstrip coupled lines in their microwave circuit models. An error function is constructed based on the even- and odd-mode analysis, impedance, transmission and scattering matrices of the phase shifter, which is a frequency...
