Abstract
A millimeter wave reflection phase shifter employs a fin-line structure within a waveguide network which has a central leg and four arms which together form two symmetric Y-junctions. The fin-line forms a septum within the waveguide and includes a conductive layer having a central gap or slot therein which extends along the leg and into each of the arms. Means for shorting the slot arms disposed at one end of the leg controls the phase shift experienced by a signal propagating through the phase shifter. This phase shifter may provide multiple selectable phase shifts.
