2-Dimensional Programmable Antenna Positioner for Antenna Pattern Measurement

Antenna Positioner is a key part of antenna far-field measurement. Such 2-dimensional positioner system is composed by azimuth axis and polarization axis. Tested antenna is fixed on the installation surface of the polarization axis, and the positioner can accurately change the mechanical point of the antenna in space, in order to achieve the test of amplitude or phase direction pattern.

* Movement mode: Azimuth, Polarization

* Rotating angle’s range: 0°~360°(Azimuth, Polarization), installed with electrical limit

* Rotating speed: Azimuth 1°/s ∼ 9°/s (0.2∼ 1.5rpm)

Polarization 1°/s - 9°/s (0.2∼ 1.5rpm)

* Minimum stepping angle: 0.2°

* Position accuracy: Azimuth ≤ ±0.2°, Polarization ≤ ±0.2°

* Translation range: 0 ~ 300mm (with scale), manual, azimuth center is the zero.

* Loading weight: Azimuth < 50Kg,Polarization < 10Kg

* Diameter of loading tray: ≥ Φ80mm

* Indoor environmental condition: 0~400C, RH≤85%

* Positioner’s controller is controlled by local or remote
