Ovsyannikov, I. Borisenko, K. Constantinian, Y. Kislinski, A. Hakhoumian, N. Pogosyan, T. Zakaryan] Thin film metal oxide superconducting bicrystal junctions on sapphire substrates with I c R N products up to 2.5 mV at 4.2 K for width 4 μm and normal-state junction resistance 10-60 Ω were fabricated and characterized at dc and THz frequency. Three types of samples—one with broadband log-periodic antenna, another with double-slot antenna for 300 GHz and third one with double-slot antenna for 400 GHz—have been investigated at THz frequency. New design of antenna coupling with Josephson junction was elaborated for minimization of THz frequency losses in superconducting film. For a particular case of f=320 GHz double-slot antenna, a ratio for bandwidth Q = f/Δf ≈ 10 was measured.
