Cs. Teoh et Le. Davis, A COMPARISON OF THE PHASE-SHIFT CHARACTERISTICS OF AXIALLY-MAGNETIZEDMICROSTRIP AND SLOTLINE ON FERRITE, IEEE transactions on magnetics, 31(6), 1995, pp. 3464-3466
Using the Finite Element Method, the propagation and phase shift chara
cteristics of shielded microstrip and slotline on an axially-magnetize
d ferrite substrate are derived and compared. Results show that when t
he two structures have identical dimensions and ferrite parameters, th
e microstrip provides approximately 2-3 times greater phase shift per
unit wavelength (of the isotropic case) than the slotline.
