 Abstract. Series and parallel arrays of ring antennas with bolometers of superconductor-insulator-normal metal-insulator-superconductor (SINIS) structures are designed, manufactured and experimentally studied. The samples are matched to the external radiation in the range of 250-380 GHz by an input conical horn, a circular waveguide with a diameter of 0.9 mm and an integrating cavity in the form of a conical horn with a counter-reflector (backshort). Spectral characteristics of such devices are numerically modelled and measured using Backward Wave Oscillator radiation source. The use of an antireflection coating on a silicon substrate improves the sensitivity and uniformity of the spectral response. The measurements were carried out in a dilution cryostat at temperatures in the range of 80-350 mK. For a series array of 25 antennas with bolometers, the voltage responsivity to blackbody radiation approaches 3·109 V/W; the linear response observed for the input power up to 5 pW. Current responsivity for a matrix of 25 parallel antennas with bolometers is 2·104 A / W.  Noise equivalent power in both cases was in the range of (3…5) ·10-17 W/Hz1/2

Keywords: NIS junction, cryogenic bolometer, integrating sphere, annular antenna, antenna array, distributed absorber, MM and SubMM waves, cryogenic receivers for radio astronomy.
