Space Antenna Mesh for Large Deployable Reflector Antennas

TEC-KNIT is developing and producing state-of-art and advanced fabrics for space technology, processing finest metal wires from gold plated molybdenum or wolfram. 

Flight Proven Mesh Technology

TEC-KNIT has been the supplier of deployable reflector mesh for several Israelic satellites since 2007, for projects such as the TecSAR and Ofeq program (latest launch of Ofeq-13 in spring 2023). Satellites like these work in X-band frequency range.

Products

With increasing frequency band width of antennas, requirements to antenna mesh are increasing as well. Therefore, TEC-KNIT received funding from European Space Agency to develop an advanced deployable antenna mesh fabric for higher radio frequencies up to Ka-band. Find a selection of available products below.

KA-BAND MESH
(> 36 GHz)

KU-KA-BAND MESH
(< 28 GHz)

X-BAND MESH
(< 12 GHz)

How TEC-KNIT is testing

All deployable mesh materials are tested for critical properties in internal laboratory and with external partners.

 

 

  • Mechanical properties (e.g. tensile strength and elasticity)
  • RF properties (e.g. reflectivity loss at specific incidence angles)
  • Properties regarding passive intermodulation (PIM)
