Abstract :
Describes a monolithic high-temperature superconductor (HTS) phase shifter integrated into a 10-GHz microstrip line. The HTS monolithic phase shifter uses over 2000 integrated (SQUID) (superconducting quantum interference device) devices per wavelength. Phase shifts of 20 degrees were observed in transmission line circuits, and phase shifts of greater than 190 degrees were observed in the resonant circuits. The high coupling limit is the best model for the circuit. This HTS phase shifter is suitable for integration into phased-array antenna systems for communications applications.<>
