摘要

我们从带偏置馈电槽天线的谐振隧道二极管(RTD)振荡器中获得了亚太赫兹振荡。无偏置时的振荡频率约为350 GHz，而当偏离天线中心15 μ m(60%)时，振荡频率约为420-440 GHz。采用三维电磁场仿真的方法，分析了槽天线RTD位置对振荡频率和输出功率的影响。由于改进了RTD与天线之间的阻抗匹配，与以前报道的无偏置馈电振荡器相比，振荡频率和输出功率大大提高。实验频率与计算值吻合较好。

Sub-THz Resonant Tunneling Diode Oscillators With Offset-Fed Slot Antenna

We obtained sub-THz oscillation from resonant tunneling diode (RTD) oscillators with offset-fed slot antennas. The oscillation frequency without offset is about 350 GHz, whereas it increases to about 420-440 GHz with offset of 15 mum (60%) from the antenna center. The dependence of the oscillation frequency and output power on RTD position along slot antenna is analyzed using 3-dimensional electromagnetic-field simulation. The oscillation frequency and output power largely increase compared with previously reported oscillators without offset feed, because of improvement on impedance matching between RTD and antenna. The experimental frequencies were in good agreement with the calculation.
