Abstract

The results of simulation of the dielectric resonator in the amplitude detector circuit with a Schottky diode in the range of 100–135 GHz are presented. It is shown that the use of Al₂O₃ hyperhemisphere on an insulating substrate makes it possible to increase the signal power in the antenna by a factor of 19 due to higher-order resonances in a narrow frequency band near 121 GHz. The resonator size is significantly smaller than the lens and does not exceed 2λ, which is much in demand for array THz detectors based on Schottky diodes.

摘要

给出了使用100-135 GHz范围内的肖特基二极管对振幅检测器电路中的介电谐振器进行仿真的结果。结果表明，在绝缘基板上使用Al ₂ O _3超半球可以使天线中的信号功率由于在121 GHz附近窄频带中的高阶谐振而增加19倍。谐振器的尺寸明显小于透镜，并且不超过2λ，这对于基于肖特基二极管的阵列THz检测器来说是非常需要的。
