Abstract
In some embodiments, a positioning system is configured to position a plurality of antennas about a device under test (DUT). According to one embodiment, a positioning system includes a first positioner configured to hold a DUT and to provide motion of the DUT about a first axis, and a second positioner configured to hold a first antenna and to provide motion of the first antenna about a second axis.
Claims8
A positioner system for use in testing a device under test, DUT, the positioning system configured to position at least one antenna about the DUT, the positioning system comprising:
- a turntable configured to hold the DUT at a first height, the turntable configured to rotate about a center axis;
- a first positioner that is concentric with the turntable and that rotates about the center axis and supports a first support unit that is fixed to a base of the first positioner so that the first support unit circles the DUT when the first positioner rotates about the center axis;
- the first support unit mounted on the first positioner and configured to circle the DUT as the first positioner rotates about the center axis, the first support unit having a first positioner arm that rotates about an axis passing through the first support unit;
- and
- the first positioner arm mounted on the first support unit and configured to rotate about the axis passing through the first support unit, the first positioner arm being configured to hold a first antenna so that when the first positioner arm rotates about the axis passing through the first support unit, the first antenna sweeps through an arc about the DUT.
A positioner system for use in testing a device under test, DUT, the positioning system configured to position at least one antenna about the DUT, the positioning system comprising:
- a first turntable configured to rotate about a center axis and to hold the DUT;
- a second turntable concentric with the first turntable and configured to rotate about the center axis and to hold a first antenna;
- and
- a third turntable concentric with the second turntable and configured to rotate about the center axis and to hold a second antenna.
