Microwave and terahertz horn antennas

TeraSense offers quite a few models of terahertz and sub-THz sources (IMPATT diodes), Each THz source can be ordered either with respective WR- output flange or with rigidly fixed conical horn antenna. A detachable horn antenna is an optional add-on element, which can be attached to a respective WR- output flange. All in all, TeraSense offers a few types of horn antennas, as described below:

W-band antennas

Terahertz antennas

Detachable diagonal horn antenna for ~300 GHz  sources

Detachable diagonal horn antenna for ~300 GHz sources

  • Frequency range: available with ~ 280 GHz – 290 GHz sources
  • Beam shape: gaussian
  • Divergence angle: +/- 9.5 degrees
  • Beam width (average): 5 mm
  • Mounting option: attached to WR-3.4 output flange
  • Weight: 0.010 kg (0.023 lbs)
  • Size: 17 x 19 mm (0.65’’ x 0.75’’ in)

In configuration with horn antennas our THz sources are used to ‘couple’ radiation to free space (free space impedance). Such horn antennas considerably enhance THz beam generated by IMPATT diode and improve their stability.
