Abstract :
This paper presents a novel method of inkjet printed Barium-Strontium-Titanate (BST) material for low-cost RF application. To demonstrate its capability in phased array antenna application, a compact continuously tunable load line phase shifter in the frequency range from 8 GHz to 10 GHz is realized. The BST thick-film is printed at the areas which interdigital capacitors are later patterned. A phase shift of 175° and the figure of merit (FoM) of 20° /dB at 10GHz are achieved. The size of the planer circuit is 8mm × 6mm.
