Comparative Testing of Devices in a Spherical Near Field System and Plane Wave Generator

Zurück zu den Ressourcen


The Plane Wave Generator (PWG) is an array of elements generating an approximately plane wave over a finite volume in the test area called Quiet Zone (QZ).

The plane wave condition can be achieved in close proximity to the array with suitably optimized complex coefficients. The PWG thus achieve far-field testing conditions in a manner similar to the Compact Antenna Test Range (CATR) but with a reduced distance to the QZ. As a complete system the PWG has the advantage of reduced physical size compared to the a CATR with equivalent testing capabilities, in particular at lower frequencies. A prototype of a dual polarized PWG has been designed, manufactured and tested in the 600MHz to 6GHz frequency range.
