It is entirely built using dielectric materials in order to remain almost neutral in terms of electromagnetic perturbation introduced by the measuring equipment.
16 sensors with detachable antennas are spread over a 60 cm diameter ring. A set of different antennas is available corresponding to your requested frequency and sensitivity ranges.
Each elementary sensor around the loop converts the electromagnetic received energy in a corresponding calibrated range of visible colors by using RGB LEDs. Each sensor has an A/D converter for backup and data mining.
The operation of the measuring equipment and the acquisition of data is done using an Android tablet PC. DC powering of the DUT can be performed either from the top and / or the bottom of the instrumented loop.

Application to the localization optimization of an antenna.
Objective : Results :
Select the most suitable antenna for maximum gain and define its optimal location. With Gyroscanfield, we were able to quickly identify the best antenna. An optimization step was carried out. Measurement duration: 1/2 Day

 

3D radiation pattern of an Iphone / Galaxy S3 / BlackBerry
Objective : Results :
Establish communication at between an iPhone and a base station simulator at a contant power and measurement of the 3D radiation pattern using the Gyroscanfield. Using the Gyroscanfield, we were able to view and acquire field strength emitted by each phone.

Comparison: SIMULATION / MEASUREMENT (Export CST > Viewer Luxondes™)
Objective : Results :

With the CST™ software, a comparison between the WiFi antenna simulation results and the real antenna radiation is directly performed by the Gyroscanfield. The free Luxondes™ viewer is used.

With CST™, we export the simulation of antenna (FFS) then import the viewer Luxondes™ allowing an efficient comparison.
Measurement duration: 1 '

RF attenuation measurement for carbon fiber plates.
Objective : Results :

Measure the HF attenuation (2.4 GHz) provided by a carbon fiber material.

Using the Gyroscanfield, we make a measurement with a reference antenna and then compare the various carbon plates.
Measurement duration: 30 '
