SAR Equipment

The specific absorption rate (SAR) is a measure of hove much energy is absorbed in the human body due to a present radio field, typically from a mobile phone. The energy is averaged over the body volume and normalized to 1g or 10g of tissue making the value watts per kilogram (W/kg).

The SAR robot moves a probe in the phantom filled with tissue simulating liquid, while a call to the mobile is made with a call box (base station emulator). The phone is placed next to the phantom, in a natural talk position (under the phantom). The equipment is placed in a shielded box, in order not to disturb the surrounding cellular/radio systems.

The SAR measurement equipment available at APNet includes the following:

  • DASY4 from SPEAG
  • SAM Twin Phantom with device holder.
  • ELI (body)
  • Probes:
    • EX3DV4  10 Mhz to 6 GHz  E-field
    • ES3DV3  10 Mhz to 4 GHz  E-field
    • ET3DV6R 10 Mhz to 2.3 Ghz E-field
    • H3DV8 10 Mhz to 800 Mhz H-field
  • Dielectric probe kit HP85070B
  • SAM Twin Phantom with device holder
    • ELI with device holder

 

Index SAR Equipment

This system is a manual setup for measuring the SAR (see also SAR Equipment).
It is mostly suited for “hot spot” finding.

  • Probe for manual movement
  • IXP050 probe

 

Large anechoic chamber

  • Size : 10m x 10m x 14m 
  • Equipped with two measurement systems:
    • A roll over azimuth range (9,5m distance)
      • Capable of carrying 150 kg.
      • Nearfield and far field measurements up to 110Ghz
    • Gantry arm system (3 m distance)
      • Nearfield measurements up to 40Ghz
      • Far field up to 110Ghz
      • small devices and persons
      • Large equipment up to 3500 kg (eg. a car).

The chamber can open the roof and side to facilitate measurements to and from space and terrestrial environment. It is possible to bring large objects like cars into the chamber.
