This article presents a design method for 5-bit digital phase shifter (PS) by using the phase-tuning property of open-/short-circuit microstrip line-loaded slot line structure. The slot line is used as the main transmission line (TL), and vertically loaded open-/short-circuit microstrip line is used...
