Abstract. Some properties of printed antennas and arrays for uncooled silicon plasmon detector arrays based on field effect transistors are shortly discussed. Antenna geometry has been optimised for maximising gain at 300 GHz. It is shown that for bow-tie antennas in the arrays in diffraction limit approximation, there are almost no cross-talks between the neighbour antennas. It is shown that the gain for one antenna is higher than that for antenna, in the array.

Keywords: bow-tie antenna, THz, FET detectors, antenna array.
