Abstract :
In this paper, a novel inkjet printing technology is presented, which allows the fabrication of fully printed tunable RF components. A tunable phase shifter is fabricated to demonstrate the capabilities of this simple, flexible and low-cost method. The proposed phase shifter contains tunable ferroelectric varactors in metal-insulator-metal (MIM) configuration, which is fully inkjet-printed on top of an alumina carrier substrate with metallic and dielectric inks. The printed phase shifter achieved phase shift of 156° at 2.8GHz (300°/cm2).
