Abstract An overview of different arrays of electrically small annular antennas of 350 GHz band with integrated superconductor-insulator-normal metal-insulator-superconductor (SINIS) detectors is presented in this paper. Arrays developed for both astronomical observations on the BTA 6 m telescope and measurements there of test sources for investigation of atmospheric turbulence to estimate its influence on the data rate of subTHz telecommunication channels. It is shown both numerically and experimentally that to simulate the electrodynamics of such non-phased antenna arrays it is necessary to investigate the whole array, not a single cell with Floquet ports. The first results of studying of superconducting antennas are also presented in this paper.

Two types arrays of ring half – wave and electrically small antennas (the typical sizes of the elements correspond to 1/10 of the wavelength) of SubTHz band with integrated Superconductor – Insulator – Normal metal – Insulator-Superconductor (SINIS) bolometers have been developed, fabricated and investigated. It is necessary to make numerical modeling of the full structure and to use additional reference channels in experimental studies for improving the accuracy of the spectral response estimations of receiving arrays. In this work, three reference channels were used for normalization: a pyroelectric receiver outside the cryostat and two cold channels – a RuO2 bolometer and chain of NIS junctions as a thermometer.
