| Popis: | The article describes a convenient way to numerically model antennas for sub-THz radiation detectors while accounting for multiple oxide layers included in typical silicon substrates used in microelectronic technologies. Several approaches are presented, including a solution based on calculations of effective permittivity of the layered substrate. The results suggest that this approach can work at lower frequencies, but will not be effective in the sub-THz range due to different mechanisms of dispersion occurring in transmission lines with homogeneous or layered substrate. |
