【Abstract】 Phase locking of Josephson junction arrays as oscillators in the millimeter wave region has been thoroughly investigated in this paper. To obtain Josephson junction array oscillator with a high frequency, narrow linewidth and high reliability, the Josephson junctions in the array must oscillate in phase. Phase locking between Josephson junctions can be completed perfectly via a integrated coupling circuit. Comparing with the dipole, slotline, and bow tie antenna, the junction with a bow tie antenna structure shows the superior performance. A circuit model of Josephson junction oscillator array is presentted.The oscillator parameters and the locking conditions are given based on the simulation results.更多还原
