  • Abstract
    A 360deg phase shifter using a tunable quasi-lumped hybrid coupler was successfully designed. The phase shifter circuit delivers two evenly-split signals phase shifted over a 368deg controllable range. The phase shifter was connected to an antenna array made with two printed patches. The feasibility of pattern reconfiguration was validated by the Sij- and radiation pattern measurements.
