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.
