摘要

太赫兹射频辐射的强度和频率很容易从超导约瑟夫森结探测器的I-V特性中推导出来。射频辐射产生与强度相关的电流阶跃。台阶处的电压精确地呈现射频频率。直流测量大大简化了检测系统。在高温超导体中实现结，只需要液氮冷却，大大降低了操作的复杂性和成本。系统效率对天线与低阻抗结之间的阻抗失配非常敏感。我们提出了改进的平面偶极天线结构，其中的结被放置在两个条带的两端之间，从偶极子中移除。对结参数对输入阻抗的影响进行了理论分析。对检测系统进行了广泛的仿真。获得了195 ~ 215GHz的高阻抗匹配，具有较高的指向性，辐射增益为5。22dB和35dB的低回波损耗。

Improved THz Reception by Non-Conventional Structure of Planar Dipole Antenna with Superconducting Josephson Junction Detector

Intensity and frequency of THz RF radiation are easily derived from superconducting Josephson junctions detectors I-V characteristics. The RF radiation generates current steps, correlated to intensity. The voltage at the steps renders accurately the RF frequency. DC measurements simplify significantly the detection systems. Implementing junctions in high temperature superconductors, requiring liquid nitrogen cooling only, reduces drastically operating complexity and cost. System efficiency is highly sensitive to impedance mismatch between antenna and low impedance junction. We propose improved planar dipole antenna structure, where the junction is placed between the ends of two strips, removed from the dipole. Theoretical RF analysis of the influence of junction parameters on input impedance was carried out. Extensive simulations of detection system were performed. High impedance matching was obtained for 195 to 215GHz, show high directivity, with radiation gain of 5. 22dB and low return losses of 35dB.
