quarter wavelength transformer with shunt stub of adjustable length
[Z1,d] = qwt3(ZL,Z0,Z2,type)
[Z1,d] = qwt3(ZL,Z0,Z2)
complex load impedance
impedance of main line
impedance of shunt stub (usually Z2=Z0)
's','o' for shorted or opened stub
impedance of 1/4-wavelength segment
qwt3 implements the design of quarter wavelength transformer with shunt stub of adjustable length
