In this paper, a novel fully printed method is presented for fabrication of phase shifter devices, aiming for phased array applications. This technology offers a simple and low cost way compared to other available technologies. The proposed phase shifter contains tunable ferroelectric varactors in metal-insulator-metal (MIM) configuration, which are fully printed on top of a carrier substrate. The printed phase shifter exhibits a figure of merit (FoM) of 70°/dB at 1.72GHz and shows a high… CONTINUE READING
