Abstract. The article presents the results of modeling various subterahertz planar antennas: broadband - log-periodic and Sinusoidal, as well as a narrow-band double-slot antenna. Various methods and approaches to modeling such structures in the CST STUDIO SUITE software package for numerical three-dimensional modeling are considered, which allow to significantly reduce the calculation time while saving the result. Also, the results of modeling such antennas on a hyperhemispherical lens are presented to improve the characteristics of the radiation pattern of such antennas. Such antennas are convenient for integrating superconducting detectors of the superconductor - insulator - normal metal - insulator - superconductor structure into them for developing new technologies for manufacturing such structures and testing primary characteristics. Such antennas can also be used for detectors of other types.
Key words: subTHz, planar antennas, broadband antennas, narrowband antennas, SINIS detectors, log-periodic antenna, sinus antenna, double-slot antenna, CST STUDIO SUITE.
