GIM05 – 3-axis spherical roll modular antenna positioner

Positioner for antenna over-the-air (OTA) mmWave and THz measurement with a spherical roll design offering the widest possible unobstructed field of view. Traditional Azimuth-Elevation positioners have arm structures on the sides of the device under test which block the measurement path at some high angles. Instead GIM05 holds the DUT from the back which completely clears the sides from obstruction and stray reflections coming from the positioner body.

ROBUST AND ACCURATE- All gears in GIM05 are made of precision machined Delrin material for higher strength, precision and long life span. GIM05 is activated by smart actuators with absolute encoders resolution below 0.1⁰.

POLARIZATION CONTROLLER- The probe side is motorized such that the probe can match the polarization of the DUT during the rolling capture sweep. It can also be programmed for any other cross polarization measurement.

MODULAR SIZE- GIM05 design allows the depth and the height to be mechanically adjusted, to accommodate various DUT size requirement. Two standard sizes are 340mm and 440mm representing the maximum diameter of the DUT when the antenna is on center.

CABLE ROUTING- To bring power, control or RF to the DUT efficiently, GIM05 provides pass-thru channels at the center o each rotation axis and numerous anchor points along the path. This way, no connectors or slip rings are needed from source to DUT.

AZIMUTH ONLY OPTION- GIM05A are positioners with only the azimuth/Theta axis motorized. Overall dimensions are the same as fully motorized versions. GIM05A is nothing else than a turntable which can be a great solution for budget-constrained setup or projects like meta-surfaces or smart reflectors.
