StarWave

MVG brings to market a new generation of 5Gmm Wave OTA testing solutions, combining smart mechanical positioners with PWGs to create accurate direct far-field conditions in a compact system. StarWave, is composed of one or several (up to seven) PWG(s) attached at a 90° angle to a vertical disk, which rotates. In front of the disk, an electromagnetically transparent mast is mounted on an azimuth positioner to support and rotate a DUT. The interface used between the mast and the DUT depends on the device, with the possibility of inserting a chair for a person holding a device.

StarWave rotates the plane wave generator(s) around the device or antenna under test to perform the elevation plane measurement. The DUT/AUT can turn in azimuth on the mastto perform the azimuth plane measurement*. The combined movements of the PWG and the DUT achieve a measure menton a complete sphere around the DUT with a minimum truncation area. This configuration improves test speed and accuracy of OTA testing. This set up also allows a device to be end-to-end tested while being worn and/or operated by a user, either standing or sitting.

Composed of hundreds of elements, the PWG has been specifically designed to create a QZ in front of its radiating surface at a distance corresponding to the radius of StarWave. The diameter of the QZ is given according to a set of parameters of the PWG. The PWG has been designed to allow wide band signal measurement and is dual-polarized for fast, accurate measurement of antenna performance criteria

The most compact solution brought to market, StarWave offers flexible, accurate and efficient testing of 5G devices.
